Hello, I am
trying to find out some information regarding an ancestor
of mine. I would like to know the name of the parents of Jasper Thomas
(he may have been named William Jasper Thomas, but was called Jasper)
he was married to Mary Obedience Boss. What I would like to know is
what Jasper's parents were named. I found some information about Mary,
that she was born in 1868 and died in 1892, if that helps. Jasper
probably would have been born around the same time as Mary I would
guess. I believe that he lived in Cooperstown.
Let me know if you need further information to find out the names of
Kathryn Seckman (grandaughter of Ruth Thomas Seckman)
