If it is the same Thomas Frederick Bigg born in 1833 Marylebone, London. He was married to Janet Emma Johnstone. He was an Anglican clergyman throughout England. He was my GGgrandfather. I'm not sure how many kids he had but I know there was my Ggrandfather Frederick Johnstone, Margaret (Peg), Maria, Lionel, Henry Reginald, Olive, Evelyn. Thomas's mother was Sarah. On the 1841 London Census she appears with Sarah 18, William 8, Thomas 6, Mary Ann 4, & Martha 2. I know that this leg of the family has a lot of Anglican clergy. There is a plaque at the church in Six Penny Handley dedicated to Thomas.
