My GG Grandfather is the James Thomas Curry on your list. My family info is that his siblings were Mattie-Nanny-Lewis and Albert. He is buried here locally. The DOB on his gravestone has 1853. However, there is conflicting family information showing that he may in fact have been born in 1838. My info is that his father was James Albert Curry married to Emma Blanchard. From my understanding Albert arrived in U.S. from Ireland with the 5 children (James Thomas,Mattie,Nanny and Lewis) However, there is obviously some problem with our info if Albert Sr. died in 1800 as you indicate. Maybe we can figure it out.
