Hello, I am also looking for any information that I can find on Toyes from Ireland. I don't know much so probably will not shed light on your search but I figure I will share what I know to see if there are any connections. My Grandmother was Marie Toye (married to John Avery they settled in Hornell,NY) she had quite a few brothers. The one brother I knew growing up was Joe Toye from Reading or Hershey,PA. He is written about and portrayed in the book and movie "Band of Brothers".My grandmother told me her parents were Irish and came to the Pennsylvania when she was around 13. That's most of what I know..not much I realize.
Hope it helps,
