I have Bucks FHS searches for Fountain covering the period from 2008. The marriages I believe were complete by then but the baptisms and burials were fairly incomplete. From the marriage results the Pitstone marriage seems the most likely, although there is a William Founteyne and Elizabeth Tatnell marriage in 1612 in Cheddington. There is also an earlier Willus Fountayn marriage to a Margaretta Tokfield in neighbouring Ivinghoe in 1592. The latter baptise children in Ivinghoe up to 1598, although Margaret is listed as wife of William on her burial in the parish in 1631 suggesting that couple stayed there. Jane Fountain wife of William was buried in Cheddington in 1649 suggesting William and Elizabeth are another couple who probably baptised children at the same time in the parish, but with no mother's name on most baptisms its a bit of an issue as to who belongs to who.

William and Jane appear to have been in Seabrooke in the parish but not all baptisms between 1608 Jane and 1625 Rebecca include the place but it seems likely some belong to them and some to William and Elizabeth. Bernard Fountain's wife Alice was buried in 1628 and is listed as being of Seabrooke suggesting the possibility that William husband of Jane is probably their son.
Edit - I have the Fountain searches as originally we thought a direct ancestor was a Fountain who married a Boarder in Eddlesborough but now seems unlikely this is the correct marriage so no Fountain connection.
