I would suggest that you check all the Shier, Shire, names you can find.I would not be surprised if you find his parents that way.My Henry Shier went to Halifax in 1783.But at least one brother stayed in NY, Julius.And his son Henry also stayed in NY. (he is my g.... grandfather.)He had a son David,b. 1809 who no one seems to know anything about.Maybe he died.I really don't know.
