:)I will probably lay claims that Catherine is the first child of William John, not John William WILMSHURST and Mary Annie Keeley. I will keep looking to try and fully verify the matter.
Catherine and George KNOTT had 8 Children, their third son Robert, born 22 Jun 1883 at Wirrabara South Australia; Mary Annie Keeley died at Wirrabara. Wirrabara is a very small town, the nucleus of the WILMSHURST family that arrived in SA settle at Thebarton, Adelaide.
I have done a check on William and Mary children, their daughters had a child at Wirrabara and the register entry was both WILMSHURST and WILMOTT, this happened a couple times with the children of William and Mary have confused the surname, like Catherine an George in the SA birth registered WILMSHURST and WILMOTT for her children.
Only 7 birth registered to William and Mary Annie, but there was eight children
This pager report below, thanks so much to Debra who found it in the Register, the article below in the Register showed that there was 2 children, one child left with friends, the births register have only one at that time, the pager report says they separated, and because Annie was pregnant with William Amos I guess got back together.
South Australian Register Saturday 18 February 1865
W. J. Wilmshurst was charged as having deserted his wife, Annie Wilmshurst, without leaving her any means of support. Complainant stated that she was married to defendant about three years ago at the Catholic Chapel, Wallaroo. Her husband did not turn her out, but the bailiff entered for rent and left her no inducement to remain. She would have become houseless and homeless but for the kindness of some friends at Thebarton. Defendant called the assistant bailiff and several other witnesses to prove the intemperate habits of his wife and her utter neglect as to his meals. The Court ordered a payment of 10s a week towards the maintenance of the wife and one child, the other being cared for by defendant's friends.
Cheers, gav
