I think the tree mentioned in one of these posts is probably my tree, 'Buckland'.
The information on Elizabeth Buckland came from the Bucks Family History Society's Baptism and Burials Database.
What I found there was this:
There were 2 Elizabeth Bucklands baptised at St Mary the Virgin, Langley Marish in 1743
13 April 1743 Elizabeth Buckland daughter of Edward and Elizabeth Buckland
11 October 1743 Elizabeth Buckland daughter of John and Ann Buckland
also
20 May 1745 Jane Buckland daughter of Edward and Elizabeth Buckland
A burial at St Mary the Virgin, Langley Marish:
22 December 1745 Elizabeth Buckland, infant, affadavit made by Mary Stedman
Perhaps this burial was of the Elizabeth whose parents were John and Ann??
