Hello again Janet
I had a chance to look at the transcriptions of the Newton St. Loe registers in Bath library today. The bad news is there was no sign of Mary Bennett (1760 - 1812)
The good news is there is more detail of Mary's wedding than shown on FreeREG.
23 Jan 1811 Newton St. Loe
Willaim Millard, bachelor and Mary Bennett, spinster (marked)
Witnesses: John Bennett, Phebe Bennett. By Banns.
There was only one other Bennett marriage:
20 Apr 1784 Newton St. Loe
John Bennett, bachelor of Corston and Susanna Pratten, spinster
Witnesses: Thos. Russell, Thos. Pratten. By Banns
Looking at the Corston registers it looks likely that John was the son of Walter and Rachel, baptised in 1758. He had a sister, an aunt and a grandmother all called Phebe. There must be a good chance that your Mary is from the same family. Hard to prove without the baptism though.
