Greetings Tony,

Unfortunately I do not know your Thomas Francis Shimmin or his son Robert Henry Shimmin. I am related to Robert Shimmin b.20 Sep 1832 Ballaugh d.1 Jul 1916 Castlemaine,Victoria,Australia through his son George Henry Shimmin b.30 Jan 1863 Castlemaine,VIC d.20 Sep 1943 East St.Kilda,Melbourne,VIC and his granddaughter Jean Shimmin b.29 May 1897 Ballarat,VIC d.5 Mar 1976 Elsternwick,Melb.VIC who was my Grandmother. I think the relations who went to USA were Edward, John and William and were based at some time in Illinois,Iowa and/or Wisconsin.
Can you check the tree you have for me to see what comes up ? You could try sending the tree by email to my alternate email address : dgoff@ferroaus.com.au as I would be most interested.
best regards

Don
