I have an ancestor who was born in 1811 in Philadelphia, per her death record and census records. She was married in Ireland and the births of her children are listed in the Quaker records in the Ulster Monthly Meetings (she had joined the Lisburn meeting). I hired the Quaker records expert at Swarthmore to look for her birth record and any other records about her family, but he couldn't find any. Are there other repositories that have Philadelphia Quaker records?
I tried on the Irish side to get the record of her presenting her removal certificate, but they have apparently lost those records from that era.
My grandmother had said that this ancestor and her parents were devout Quakers. She left Philadelphia for Ireland after her parents died (to live with a cousin).
Here are the particulars: Her name was Isabella Johnson Green and her parents were Richard Green and Sarah Johnson.
