I am trying to trace the family of my grandmother.Her great grandmother arrived in Australia with 4 children. Her name was Janet Aitken (Bertram) she arrived without her husband (John)and it seems that one of her children did not make the trip although I cannot find out why.It seems that her husband never made it to Australia and I cannot understand this.Her children were Elizabeth Barclay b 1850 ??? William b 1851 Robert Lockhart b 1854 Margaret Somerville b 1856 Andrew Bertram b 1858 All the children were born in Glasgow, Scotland. If anyone knows anything about this family at all.I would greatly appreciate any assistance.
