I am searching for descendants of the children of William Reid and Alexina Margaret Murray Ewing Reid of Scotland who emigrated to Australia in the 1800s.

The children who emigrated to Australia were

Isabel Ewing Reid born 14.04.1881 (searching for her kids and descendants)
Willaim Rounsfell Reid born 27.02.1890 (searching for his kids and descendants)
John Alexander Blair Reid died 08.11.1949 and had two children in Australia Sheila and Ailsa. Sheila married a Sheehan and Ailsa a Patterson.(searching for children and descendants)

Appreciate any assistance anyone can give me.
