While searching for Grosset/ts, came across the Renfrew, Scotland, web page on the USGenWeb/WorldGenWeb - and your reponse on the Australia,General Australia Query Forum regarding William Wallace; saw the other surnames that you were interested in - including Grosset and Isaacs. While doing research on our particular branch of Grosset/ts - am also assisting in the research of another Grosset family - which contains the marriage of Georgina Agnes ISAACS on 27 January 1878 to Adam William GROSSET, who was born 3 September 1855, in Airdrie, Scotland and died, in Scotland, on 22 December 1887. They had five children: Mary Wilson Adam, William Arthur, James Adam, Georgina E and Beatrice A.
The children were born between 1879-1889; [Beatrice's birth date is two years after her father's date of death]. Both sons died in childhood. Are you acquainted with Lois Saleeba, of Croydon, Victoria? Her web page is :

Hope this is helpful information for you. Lois's Grossets are traced back to Thomas Groser of Peebles, ca 1655. My branch starts with John Grosset/Mary Murray of Dalkeith,nr Edinburgh. He was a shoemaker. David Grossett, San Antonio, Texas.
