I'm seeking any information on the lineage of my gg-grandparents, David Yarnell (1825-1896 and his wife, Isabella Dubbs Yarnell (1826-1918). They lived and raised their family in and around Allegheny County, PA but may have had an Ohio connection since my g-grandmother (Molly Yarnell Bartley) was born in Samem, Ohio. Any info will be greatly appreciated and may be emailed direct to grnthmbs34@gmail.com. Thanks!
