I hope this gets to Brigitte,who is searching Thomas Gibson In Missouri. I am pretty sure that I have found your Thomas Gibson wife Mary in 1850 census Reynolds Co Mo. Possibly the son of John Gibson and wife Hannah,who live just 2 houses away. In 1860, I find Hannah Gibson and 3 sons , and near is Thomas Gibson ,wife Mary A and daughter Margaret age 9, and 3 more children in St Francis Co. In 1870 Thomas is then married to Permelia with probably 3 children by this 2nd wife and then children by 1st wife, Margaret, Edna, John, William.This is still St Francis Co. Thomas ,wife and 4 children are still in St Francis Co in 1880 census. Contact [email protected] if you are interested in what I have found. Mina in Missouri
