Thank you, the place is Duckmire, I've found it mentioned in other records but haven't pinned down where in Slaidburn it was yet. I think Robert is his brother, John was born about 1652 from his age at death and the Slaidburn register doesn't survive from that period but I have a baptism for Robert to William Battersby of Duckmire in 1665 so I think it's likely they're the same family especially with them both becoming quakers. The Robert Parker is puzzling me, Clement Parker was the son of a Robert but that Robert would be at least 80 at this date, so I'm wondering if it's a brother I haven't found.
