So to summarise what we collectively know: Horace Lankester Scarr was born on 05 Apr 1877 in Brisbane, son of William Scarr and Helen Lankester, so he's not the chap who dies in NSW in 1949. He marries Ruth Jessie JOSEY (divorced ex-wife of William Albury) on 01 Sep 1900 in Brisbane. They had a lot of children but later separated. And we see in 1922 they are at different addresses in the electoral roll and apparently in 1925 Horace changes his name and disappears from the electoral rolls (I can't find him after 1922 anyway). In 1947 he writes to request war medals. He was a travelling optometrist so his comments about "knocking about" and using a "c/o GPO" address in 1948 may be consistent with that. I presume he used the name Scarr when writing in 1947 because his army records would be in that name. Kerry
