Thanks Sparrett, I'm trying to find the children to Kate Ada nee Johnston. Kate was born in Launceston, Tasmania. The family moved to Melbourne early 1900 (Kate was around 15) and Kate married Sommerton from SA. Later around 1925 she married (2) Alfred Ashworth in Melbourne and moved to NSW where she lived her remaining years.
I'm trying to find any children she may have had to Sommerton either in SA or VIC.
I am not sure that her marriage to Alfred Ernest ASHWORTH went well for her.
Interestingly they lived in 1930 at
Johnston St, number 270 in Kentville NSW and he was a builder..

There seem to have been at least one child, a boy who was resued from a house fire.

A search of his name on Trove brings up the troubles with the law, drink-driving, use of aliases
(Wadsworth, A. B. Lane) (Police Gazette NSW) a divorce in earlier life and sundry other snips.
I'm not sure how relevant this information is to your inquiry, but his name in the search box will tell much
