I have a (Clara / Sofia?) Yarling born around 1846 in Counhessen (Covenhessen? Stupid census takers can't write well...) Germany, who at some point immigrated and was living with (married?) my 3grts grandfather Franz Josef Schaner. They lived in Covington Kentucky and between 1860 and 1864 moved to Wheeling, Orange County, West Virginia.
I am having a devil of a time tracking this woman. Census records state her name was Sofia b1846, but family lore/information, and even her own children's death records, state her name was Clara Yarling (also born 1846). My grandmother's genealogical records state she died in 1870 (KY or WV?), but then "Sofia Schaner" is listed in Wheeling, West Virginia, in 1880. *sigh*
Anyway, I doubt this will help you much, but at least you know your not alone when having trouble identifying "Yarling" ancestors!
