My 2nd great grandmother's sister Elizabeth Cannell Shackleton (married to Hodgen Shackelton) had children named Thomas (20), Henry (16), William (14), John (9), and Margaret (7) --- ages from the 1881 Census. They were from Liverpool. Hodgen and Elizabeth Shackelton's grandson Thomas Albert Hodgen Shackleton immigrated to Australia with his family in 1954, so post-war as you indicated in your post. I don't know whose son Thomas Albert was. I don't know if this is the same family, but thought I'd share the information.
