I am answering this post for informational purposes long after it was posted.I do not believe that the maiden name of Anna Hollingsworth Parker Beeler Fulps was Hacker.Our Hacker line begins with Julius Hacker who married Martha Beeler, and they had seven children--Julius Jr., John, Jacob, Elizabeth, Joseph, Susan, and Catherine.These children were born between 1765 and 1783.
I'm not sure who the Jacob Hacker living in Grainger County in 1808 was.Julius and Martha's son, Jacob, was living in Greene County with his wife, Martha Register Hacker, at that time.Jacob's son, Jacob, would have been too young to be living on his own.However, John Hacker--also Julius and Martha's son--lived in Grainger County during that decade (aft 1800 to abt 1810); his name appears on Grainger County tax lists.
I think that Joseph Beeler, s/o John Valentine Beeler, owned land on Williams Creek, Grainger County around that time.He was the 3rd husband of Anna Hollingsworth Parker Beeler Fulks.
Jacob Hacker was not the father of George Hacker, husband of Rebecca Hollingsworth.George's father was Joseph Hacker, s/o Julius and Martha Beeler Hacker.Joseph Hacker was married to Patricia Haggerty, and they settled in Roane County, Tennessee after 1810.George W. Hacker was probably born in that county.But he and Rebecca were married in Grainger County.His brother, Julius C. Hacker--who married Elizabeth Beeler--also lived in Grainger County from abt 1833 to 1859.
Finally, the "Valentine" referred to in the earlier post was probably Valentine Hacker, s/o John Hacker--brother of Joseph and Jacob Hacker.He was born in Grainger County abt 1804, while his father and mother lived there.He might have been named after John Valentine Beeler, uncle of the Hacker brothers.
