My GGG Granfather, Andrew Donaldson (1752-1817), married a woman named Isabella in 1794. Isabella was born in 1772 in Cumberland County, PA and died in 1825. But I don't know her last name or who her parents were. If you do, please fill me in. I'd be ever so grateful.

My GG Grandmother, Mariah Cline, married John L. Willaimson in 1848. She was born in Ohio in 1830 and died in WV in 1921. If anyone knows anything about her parents, I'd love to know. Thanks so much.

My G Grandmother, Dorcas Phebe Critchfield, was born in Greene County, Pennsylvania in 1860, married William Edgar Linger in November of 1880, and moved to West Virginia, where she died in February of 1944. Her mother, by all family Bible accounts was Ellen Main and her father was apparently John Critchfield. Other than that, I have no information about her parents or earlier relatives. If you can help I'd be grateful.

My GGGG Grandmother was Margaret McNemar Linger, who lived from 1764 to 1827 in West Virginia. I'm looking for her father, Philip and for Philip's wife, whatever her name might be. Any help will be appreciated. Thanks.
