I hope someone can help me with a question concerning a possible Alder/Lindsay marriage in early Prince Georges County. I have my Alder genealogy traced to Prince Georges Co, MD, but I've been stumped for 30 years at George Alder who died there in 1737. I have a theory that George Alder's mother was of the Lindsay family (other spellings Lindsey, Linsey, Linsy, Linzy, etc.), but I have no solid proof of this yet. Let me explain my theory, and perhaps someone could shed some light on it, refer me to specific researchers, or steer me in a different direction...

George Alder (d. 1737 Prince Georges Co., Maryland) married Elizabeth Keech (d. 1786 Prince Georges Co., Maryland). They were married 16 Dec 1729 in Piscataway, Prince Georges Co. The 4 children of George and Elizabeth (Keech) Alder, all born in St. John's Parish, Prince Georges Co. were:

1) James Alder (b. 7 Oct 1730; d. 29 Nov 1775 PG Co.; m. Elizabeth Latimer)
2) Bowles Alder (b. 5 Jan 1732)
3) Ruth Hawkins Alder (b. 24 Mar 1735)
4) Mary Lindzy Alder (b. 12 Oct 1737)

I found that the parents of Elizabeth (Keech) Alder were James Keech and Ruth Hawkins, of Charles County, Maryland. Note that George and Elizabeth Alder named their first daughter Ruth Hawkins Alder, ostensibly after her maternal grandmother. So, it stands to reason that their other daughter, Mary Lindzy Alder, may have been named after her paternal grandmother (Mary Lindsey?). I did find on the familysearch.org website the name Mary Elizabeth Lindsay, child of James Lindsay and Mary Troope, born ca 1662 in Charles Co., MD. I don't yet know the original source of this information (so I treat it only as a possible clue) or whether this Mary Elizabeth Lindsay was even married to the father of George Alder, but it is an intriguing idea. Does any information exist on an Alder/Lindsay connection from this time period? Thanks in advance, and here are the websites mentioned above:
