Karen:I am researching the "Old Mike" TeetsLineage also.
My husband's Gt. Gt. Aunt, Mahalia Birch, md. Christian Teets abt. 1829 in Preston Co. area.
The Preston Co. Hist. Soc. has told us that Christian was indeed a son of "Old Mike" Teets, his name having appeared on a store account for "Old Mike".Janice Cole Sisler said she had found 3 sons of Old Mike who had not been named in the Preston Co. Hist. books, one of them being Christian. In 1850 Christian & Mahalia lived in Green Co. PA & from there they went to Bracken Co. KY where they both died & are buried.
Please contact me privately if you wish to further compare notes on this Teets/Birch family. (email@example.com
