Ecclesiastical History, book 3 mentions this Theophilus of Caesarea (Maritima) along with the bishop of Jerusalem (Narcissus) and of Tyre, modern-day Lebanon (Cassius).
CHAPTER XXIII.—The Question then agitated concerning the Passover.
1. A QUESTION of no small importance arose at that time. For the parishes of all Asia, as from an older tradition, held that the fourteenth day of the moon, on which day the Jews were commanded to sacrifice the lamb, should be observed as the feast of the Saviour’s passover. It was therefore necessary to end their fast on that day, whatever day of the week it should happen to be. But it was not the custom of the churches in the rest of the world to end it at this time, as they observed the practice which, from apostolic tradition, has prevailed to the present time, of terminating the fast on no other day than on that of the resurrection of our Saviour. 2. Synods and assemblies of bishops were held on this account, and all, with one consent, through mutual correspondence drew up an ecclesiastical decree, that the mystery of the resurrection of the Lord should be celebrated on no other but the Lord’s day, and that we should observe the close of the paschal fast on this day only. There is still extant a writing of those who were then assembled in Palestine, over whom Theophilus, bishop of Cæsarea, and Narcissus, bishop of Jerusalem, presided. And there is also another writing extant of those who were assembled at Rome to consider the same question, which bears the name of Bishop Victor; also of the bishops in Pontus over whom Palmas, as the oldest, presided; and of the parishes in Gaul of which Irenæus was bishop, and of those in Osrhoëne and the cities there; and a personal letter of Bacchylus, bishop of the church at Corinth, and of a great many others, who uttered the same opinion and judgment, and cast the same vote. 3. And that which has been given above was their unanimous decision.
The letter "of those who were then assembled in Palestine" is quoted later (apparently, together with a bishop from Tyre and from Ptolemais in Cyrenaica).
CHAPTER XXV.—How All came to an Agreement respecting the Passover.
1. THOSE in Palestine whom we have recently mentioned, Narcissus and Theophilus, and with them Cassius, bishop of the church of Tyre, and Clarus of the church of Ptolemais, and those who met with them, having stated many things respecting the tradition concerning the passover which had come to them in succession from the apostles, at the close of their writing add these words: 2. “Endeavor to send copies of our letter to every church, that we may not furnish occasion to those who easily deceive their souls. We show you indeed that also in Alexandria they keep it on the same day that we do. For letters are carried from us to them and from them to us, so that in the same manner and at the same time we keep the sacred day.”
This entire part is a wealth of 'geographical information' for those interested in it. Here is the 24th chapter inbetween.
CHAPTER XXIV.—The Disagreement in Asia.
1. BUT the bishops of Asia, led by Polycrates, decided to hold to the old custom handed down to them. He himself, in a letter which he addressed to Victor and the church of Rome, set forth in the following words the tradition which had come down to him: 2. “We observe the exact day; neither adding, nor taking away. For in Asia also great lights have fallen asleep, which shall rise again on the day of the Lord’s coming, when he shall come with glory from heaven, and shall seek out all the saints. Among these are Philip, one of the twelve apostles, who fell asleep in Hierapolis; and his two aged virgin daughters, and another daughter, who lived in the Holy Spirit and now rests at Ephesus; and, moreover, John, who was both a witness and a teacher, who reclined upon the bosom of the Lord, and, being a priest, wore the sacerdotal plate. 3. He fell asleep at Ephesus. 4. And Polycarp in Smyrna, who was a bishop and martyr; and Thraseas, bishop and martyr from Eumenia, who fell asleep in Smyrna. 5. Why need I mention the bishop and martyr Sagaris who fell asleep in Laodicea, or the blessed Papirius, or Melito, the Eunuch who lived altogether in the Holy Spirit, and who lies in Sardis, awaiting the episcopate from heaven, when he shall rise from the dead? 6. All these observed the fourteenth day of the passover according to the Gospel, deviating in no respect, but following the rule of faith. And I also, Polycrates, the least of you all, do according to the tradition of my relatives, some of whom I have closely followed. For seven of my relatives were bishops; and I am the eighth. And my relatives always observed the day when the people put away the leaven. 7. I, therefore, brethren, who have lived sixty-five years in the Lord, and have met with the brethren throughout the world, and have gone through every Holy Scripture, am not affrighted by terrifying words. For those greater than I have said ‘We ought to obey God rather than man.’” 8. He then writes of all the bishops who were present with him and thought as he did. His words are as follows: “I could mention the bishops who were present, whom I summoned at your desire; whose names, should I write them, would constitute a great multitude. And they, beholding my littleness, gave their consent to the letter, knowing that I did not bear my gray hairs in vain, but had always governed my life by the Lord Jesus.” 9. Thereupon Victor, who presided over the church at Rome, immediately attempted to cut off from the common unity the parishes of all Asia, with the churches that agreed with them, as heterodox; and he wrote letters and declared all the brethren there wholly excommunicate. 10. But this did not please all the bishops. And they besought him to consider the things of peace, and of neighborly unity and love. Words of theirs are extant, sharply rebuking Victor. 11. Among them was Irenæus, who, sending letters in the name of the brethren in Gaul over whom he presided, maintained that the mystery of the resurrection of the Lord should be observed only on the Lord’s day. He fittingly admonishes Victor that he should not cut off whole churches of God which observed the tradition of an ancient custom and after many other words he proceeds as follows: 12. “For the controversy is not only concerning the day, but also concerning the very manner of the fast. For some think that they should fast one day, others two, yet others more; some, moreover, count their day as consisting of forty hours day and night. 13. And this variety in its observance has not originated in our time; but long before in that of our ancestors. It is likely that they did not hold to strict accuracy, and thus formed a custom for their posterity according to their own simplicity and peculiar mode. Yet all of these lived none the less in peace, and we also live in peace with one another; and the disagreement in regard to the fast confirms the agreement in the faith.” 14. He adds to this the following account, which I may properly insert: “Among these were the presbyters before Soter, who presided over the church which thou now rulest. We mean Anicetus, and Pius, and Hyginus, and Telesphorus, and Xystus. They neither observed it themselves, nor did they permit those after them to do so. And yet though not observing it, they were none the less at peace with those who came to them from the parishes in which it was observed; although this observance was more opposed to those who did not observe it. 15. But none were ever cast out on account of this form; but the presbyters before thee who did not observe it, sent the eucharist to those of other parishes who observed it. 16. And when the blessed Polycarp was at Rome in the time of Anicetus, and they disagreed a little about certain other things, they immediately made peace with one another, not caring to quarrel over this matter. For neither could Anicetus persuade Polycarp not to observe what he had always observed with John the disciple of our Lord, and the other apostles with whom he had associated; neither could Polycarp persuade Anicetus to observe it as he said that he ought to follow the customs of the presbyters that had preceded him. 17. But though matters were in this shape, they communed together, and Anicetus conceded the administration of the eucharist in the church to Polycarp, manifestly as a mark of respect. And they parted from each other in peace, both those who observed, and those who did not, maintaining the peace of the whole church.” 18. Thus Irenæus, who truly was well named, became a peacemaker in this matter, exhorting and negotiating in this way in behalf of the peace of the churches. And he conferred by letter about this mooted question, not only with Victor, but also with most of the other rulers of the churches.

It may be interesting to note that the
churches of Asia, even in the later account of Eusebius (which cannot be claimed to be biased in favor of the opinion of Polycrates of Ephesus), were still merely just preserving "
the old custom handed down to them." And that Victor was breaking with Roman tradition by refusing to recognize the validity of the practice in Asia Minor.
(It is not completely certain that the Roman tradition was an innovation in approximately the time of Anicetus, when Polycarp opposed him. ... But it seems to be the most likely interpretation. In the letter quoted from Irenaeus, both the attempt of Anicetus to convice Polycarp and the attempt of Polycarp to convince Anicetus are phrased in such a way that makes Polycarp's practice seem more ancient--"neither could Anicetus persuade Polycarp
not to observe what he had always observed with John the disciple of our Lord, and the other apostles with whom he had associated" and "neither could Polycarp persuade Anicetus
to observe it as he said that he ought to follow the customs of the presbyters that had preceded him.")
