My 5th Great Grandfather was James Barclay, born 1722 died 1792. He was buried at the Neshaminy Church in Warminster, PA. His wife was Margret Craig Fowler. After his death, she moved in with her son James(1752-1810) in Philadelphia. She is buried at Laurel Hill in Philadelphia. Family history says the Barclay house had a fire which destroyed many of the records. We have never been able to successfuly trace James' lineage back further.
From what I understand, Hugh moved west out to Greene County.
