The correct name for the woman that you are speaking of is "Leah" Wilson-Perryman, not Lear.
Isaac Perryman was an uncle of mines. His brother, James Perryman that married the Lipan-Apache Princess Teresita was my gg grandfather. Please let me know if I can be of assistance to you on your search. I have quite a bit of info on the Perryman Family.email@example.com
