I've no doubt you're not the only one. You really almost have to draw a picture. By the mid 1700s they start to peter out. Charles Barham d. 1683 was the first one in his line of the family to be so named. Lots of them in England in the mid 1620s with the crowning of Charles I of England in 1625. That, and the birth order of his siblings, helps place his birth year as 1625/6. There is no known baptismal record for him in either his home parish (Boughton Monchelsea---some people still copy/pasting "Broughton"--no such place!) nor that of his maternal grandparents, Sir Edward and Dame Elizabeth Filmer (East Sutton). People REALLY should put an asterisk next to 1626 when they cite it as being the birth year. The Barhams and Filmers both were hard-core King and Country cavaliers, with histories of royal appointments on one side, and knighthoods on the other.
