In Dublin, the bus routes are bilingual and a couple of years ago I noticed that the Irish translation of Harristown is Baile Anraí¹. When I first saw “Baile Anraí” as the destination for a passing bus, I wondered where Henry’s Town might be. I then figured that Henry and Harris must be variations of the same name and that Anraí is the Irish version of both names.
Sure enough, when I check this now, Wikipedia concurs². The article it cites states that Harry is the “Medieval English form of Henry. In modern times it is used as a diminutive of both Henry and names beginning with Har.”³
The surname Hanks may also derive from the use of Hank as a diminutive of Henry⁴
