What is confusing is that in that orphans petition, it is stated that Jane Lockry was already married to Daniel Harkin (I can understand that the name could be Forkin). That was in 1736. However, the marriage listed at the Philadelphia Church is from 1744. When did Jane remarry? Could Giles/Jane be the daughter of James and Jane? or someone else all together?
