Brian,
I found your book about 20 years ago in the State Library. It mentions the mother of the husband of a 1st cousin once removed of mine.
On page 350, Rosa Hannah Leask is noted as having married John Harrison. The had a son, John Walter Harrison who married Dorothy Isobel Holding, my cousin. John Walter H was born 23rd may 1921 and has just passed away on the 19 January 2012.
Regards,
Peter Gamble
