It must be noted, against this statement of the art historian Percy Brown alleging an Albanian origin of Sinan, that in the Sinan bibliography up to the issuance of Brown's book in 1942 an Albanian origin of Sinan had been never assumed, that the Christians in the Kayseri region in Asiatic Turkey had been at that time almost exclusively ethnic Greeks and Armenians (even if speaking Turkish) who had lived for almost 2,000 years in this region and that no immigration of Albanians to the region up to that time is known.
