So nice to hear from you & get your note about Hannah Twomey/Townley. I got the Townley name from my great grandmother's reseach notes (Leah Patterson McKeown Malott was her great grandmother.)
I would love to fill in some vital statistics on John McKeown & Catherine Patterson's family. I know that John died in 1816 in Corydon, IN of potaime, but don't have an actual date. I show Catherine May 14, 1788 - December 15, 1855 & that they m. in Jefferson Co., KY on December 20, 1809. Children: Rachel (unknown dates or marriages) Eliza b. c. 1810 m. Simeon Pottorff Robert P McKeown b. c. 1812 m. Hannah Twomey or Hannah Townley (Do you know her parents?) Delilah K. b. c. `8`4 m. Peter Maple Leah Patterson McKeown b. June 08, 1816 m. William Henry Malott (my line.)
Wish I could get to Jefferson Co., KY to do more lookups on this line! I don't have all of the children's dates either for Leah & William Henry Malott either.
