I am following this family line as well....I've looked at the Felsted parish transcript for 1735, the marriage for Thomas Livermore and Ann Rumsey as written thus
" May 13 Thomas Livermore and Ann Rumsey were married" later on the same page and in the same hand is written
"Oct 6th Tho Livermore and Ann Smith were married"
I wonder if the second 'Tho' is not 'Thomas', but a shortened version of some other name, perhaps Theodore (if that was a name in use there and then), or something similar
