I was researching in the Chester Co. Courthouse files, for my husband's ancestry.I have some info on the names you listed.Lydia Bossert was born in E. Vincent 9/28/1818.She married Joseph Buckwalter 11/23/1843.She died 8/??/1916 in Mt. Carroll, Illinois.Lydia's parents were Andrew Bossert and Catherine Grubb.I have found conflicting info about their dates, so I suspect that there might have been more than one couple named Andrew and Catherine.Do you know of any siblings that Lydia had?It looks as though she might have had 2 brothers, but we have conflicting dates, so I am not sure.If I can document the lineage, it looks as though my husband might be decended from one of Lydia's brothers.I would appreciate any info you have. Thanks!
