Michael Purkey was s/o Christian. All Christian's children were by Catharina Diehlin as far as I know. He and Rachel who wed in 1800 had 2 girls born between 1800 and 1805 but do not their names. I believe I read that Eliza McKee was born in Pa. as well as Isaac. After Isaac's death, she wed a neighbor, John Walker a widower.Some of Isaac's children went to live with aunts and uncles and George Petty after he died. Isaac's siblings were: John (1797) David (1822), Elizabeth Estes, Margaret Crosby, Mary Noe, Catherine Noe, Sarah Riggs, and Daniel. You can find Michael's will or portion of it Grainger Co. Archives on line.
