I have a William Schaw who was b. in 1850 in Scotland. He went to Australia where he married Mary Sophia Beaumont in 1866. They had 3 children; Edward Thomas, Nellie & Minnie before they immigrated to America where they are listed in the 1880 Sacramento, Sacramento, California census.
Mary Sophia was born ca 1845 in England before her parents immigrated to Australia.
If you have any information regarding this family I would greatly appreciate hearing from you. I haven't been able to find where they died in America yet or who William's parents are.
