Hi, Ken! The Seabrooks I am looking for were wine merchants, so I assume it's the same family. The first one I know about is Thomas Claudius S who married Dorothy Sidell (or Seidell) Baird in Geelong, Vic in 1915. They had the following: Dorothy Lillianb. 1916 Thomas Cameronb. 1917 Marjorie Florab. 1920 Claudia Maryb. abt 1926.
I am related to the Bairds, and am looking for descendents, so that we can compare notes.
