Maybe the original message is now too old, but, I have an RGC Soady in my tree b.1854 in Dublin; Midshipman at sea, HMS Columbine according to 1871 Census. I suspect his father was Robert b. 1828 Ireland, son of Joseph b. 1602 Looe, Cornwall and Jane Boll b. 1806 Wemouth, Dorset. Joeseph was a coastguard in Ireland and the Scilly Isles.
I further suspect his name to Robert Gardener C Soady-his G GM was Sophia Gardener.
