I don't have anything specific on Margaret or Sophia Trigg, but I do have a little information on the Triggs in general in the Abenhall, Westbury and Newnham area. I suspect that they connect to two separate Thomas Trigg gentlemen in the 17th and 18th centuries. If you are interested, I can look the information out, but his would be best done off list as it might be voluminous - so by all means email me at [Deleted by admin - see Posting Guidelines]
