I think I've the skeleton of Casey's family tree ( from Casey's time at least). Richard \Dick Casey marries Mary Catherine Goodwin cf notice in the Age in 1940 recording Mrs Casey's death at age 55, which suggests she was born in 1885 http://nla.gov.au/nla.news-article204421281 This notice refers to her brother Thomas and her sister Alice O'Laughlin. This notice also records that she had 8 children Mary (said to be one Mrs McPerson, another notice credits Agnes to be Mrs McPerson but that variation is of little import) Alice who marries the son of Billy Gent, W Gent, and has 4 children and dies in 1945 ( Record 2 June 1945 ) James Thomas who is made executor of his mother's will and whose name is recorded as James Thomas Casey). He is also active in Labour Party politics. Agnes Catherine Josephine Eileen Teresa Now the oddities. If you look at the death notice of Dick Casey set out a post or two above, daughters Eileen and Teresa are not mentioned. This may be because she was pregnant at the time. She may have remarried although there is nothing to suggest this. I cannot supply the answer. A mother with 6 kids and 2 on the way may indeed be the subject of some support as it is recorded the VFL and other organisations provided. She may also have then, as it may be the case from the address in Dick's death notice have moved under the wing of the greater Casey family at Moray Street in South Melbourne as a result of the untimely death of her husband due to influenza. The death notice for Dick Casey records no siblings of Dick which is strange. Besides being a tragic story ( probably no less tragic than any other from the flu at that time, this offers us some clues as to how to get Dick's details of date of birth and parentage, if it is possible, being: (a) Birth certificates of the respective children will record particulars of the father. There are 8 children so there should be ample evidence there. (b) Family trees, to the extent any have been done; (c) Probate details in relation to the death of Mrs Casey; (d) Post office directories\electoral roll searches of the individual and his family and of those living at 126 Moray Street. Now I found this intriguing, possibly incorrect or irrelevant post,on geneological forum in relation to the Casy family, which I reproduce below in its entirety: "Hello From NZ My Great Granny had a half brother Richard Baxter Casey born in Cork Ireland. I have recently traced him to Australia where he married Mary Elizabeth Chaplin--( Born Cork--) in 1873. They had 6 children that I know of Edward Chaplin Casey 1874 Beechworth Henrietta Casey 1875 Worhouly Ada Mary Casey 1878 Whorhouly Leslie Walter Casey Richard Baxter Casey 1885 Melbourne Frederick George Casey 1888 Richmond" For those interested Worhouly is in the Wangaratta area. What interested me was in the Ancestry searches ( such as I could do them on Casey and 126 Moray Street South Melbourne. the first 2 entries were the gravestone of Leslie Walter Casey 1883 -1949 and the death certificate ( which I could not read as I do not have access to Ancestry) of one Lesley Walter Casey 1882 -1949) which would appear to be the same person and those two references, could match the above post which I've set out. Incidentally that search also comes up with electoral roll searches of Mary Catherine Casey in about 1927 and James Thomas Joseph Casey. The answer to Dick Casey's date of birth is likely not found in his football career. That tells you only that he played for South Melbourne and before that Brunswick ( and first appears , it is assumed, for Brunswick in 1899). Even if he started at 17 in 1899, that would suggest a birthdate of 1882.
