There seems to be a consensus in several unreferenced trees out there that a Thomas Louch (sometimes Loutch, Lowch etc) was born somewhere in Berkshire about 1735 and was the son of Bryant (sometimes Briant) and Susanna (nee Culham).
His parents were married on 13 October 1734 at Besselsleigh. Christenings for six (or five) other children for this couple appear in the indexes at FamilySearch; the others were baptised at either Besselsleigh or Cumnor, between 1738 and 1756. However, Thomas does not seem to make an appearance in parish registers anywhere – until his marriage to Susanna Salisbury, on 9 November 1760, at St Andrew's Church, Headington.
Some trees suggest that Thomas was born and/or died at "Sandford" (logically, Dry Sandford or Sandford-on-Thames, although other trees suggest the lesser known, and less likely, Sanford in Sonning). Some give a date of 4 January 1735 (while others say 1 April – probably a transposition).
I would be grateful for any suggestions or references that anyone has at hand. Thank you.
