Aberdeenshire Ewen family

I am trying to find living relatives of Annie Mitchell Ewen born 1913 who married Alexander Wallace Sim in 1934, had 9 children and emigrated to Tasmania in 1954.Annie's parents were Alexander Ewen (circa 1875) and Annie Ewen m.s Mitchell (circa 1878).Her Grandparents were John and Elizabeth Ewen m.s Thomson.

Any help would be greatly appreciated
