John Cashore (born 1824 in Co. Fermanagh) is my 2-great grandfather. We have very little information about his family but a cousin just yesterday told me about a 1/2 brother connection to the name Gregory that i find here on your post. She also thinks he had siblings, including a brother who went to New York (your Thomas?). John went to Ontario after marrying Elizabeth "Bessie" Rinn (from Co. Fermanagh)shipboard enroute to Ontario, Canada.
