I have a Quaker ancestor named Valentine Hollingsworth who was married to Ann Calvert. In researching her CALVERT lineage I determined with a fair amount of certainty that she was the grandniece of the Lord Baltimore George Calvert. Also, in the book "Immigration of the Irish Quakers in Pennsylvania" is the information that this couple was caught in the middle of this Penn/Calvert boundary dispute involving Cecil County, MD and Chester County, PA since she was related to the Calverts who founded Maryland and he was close to William Penn (was given 1000 acres in New Castle County, DE by William Penn when he came here from Ireland). So it does make you wonder how many of the Quaker Calverts were related to the Lords Baltimore. Ruth Gravitt
