Hi, My husband is descended from the John Lovell and Union Lee that you mentioned who settled in Barnes. They married in 1819 in Finchley. That family is well documented so they are definitely not the same couple, but trying to find the ancestry of our John Lovell (born about 1797) is difficult. There are people who have added ancestors to their ancestry tree for him but I am doubtful.... There must be a relationship between your Thomas Lovell & Union Bosworth because we have some distant DNA matches which show it. But finding out how is the difficult bit. I wrote an article on the 'Lovells of Barnes' a long time ago, which was on the Romany Genes site, but I think that site has disappeared now. alison (if anyone wants it message me and I will work out how to get it to you)
