Ann, I have Thomas Seabrook in my tree. Born Jan 4, 1857 in London. He had 2 siblings, Jessey and Henry, and 2 half siblings, Arthur Rivers and Sarah Jane (my GG-Grandmother). their father was Arthur Seabrook, but i have no info on him. THomas's mother was Mary Ann (nee)Stewart (b.jun 10 1823, d.Mar 16 1863). Not sure if this helps, but let me know.
