In addition to Thomas, there was a Richard Simpers who also appears in the 1690s era in records of Cecil Co.,MD. Land records for Cecil Co on Sept 16, 1687 refer to Richard Simpers and his wife Ann, widow of the late John Cockerkill as executors of his estate. (The inventory for John Cockerell was taken 3 Jan 1686 and the administrarix was Ann Cockerell. (thus John died intestate).
From the little data known it appears probable that either Richard or Thomas was the father of Thomas Simpers who married Amy Lewis. (at least Richard Lewis' will called Thomas a son-in-law and we are guessing that Amy was his daughter) Also there is no clear data as to the relationship between RIchard and Thomas Simpers/Sympers, except they both lived in Cecil Co in the early 1690s.
