I found Angus McLeod in the 1881 census for Tarbet, Ross-shire. He is married to Mary Ross and they have three children with them: Rachel 1854, Murdoch 1861, and George 1868.
In looking at Lochbroom births I found an Angus born to father Allan McLeod (I believe his mother is likely Christian McLeod).
On investigation I noted two different Allans. There is an Allan McLeod who married Christian McLeod 16 Jan 1815 and an Allan MacLeod, feuar, who married Isobel or Isabella Graham 11 Feb 1819 in Lochbroom.
I don't know if either family ever went to Australia.
The Alan used on FamilySearch.org ID M9YJ-58R
https://www.familysearch.org/tree/pedigree/landscape/M9YJ-58Ris from Killearnan, ROC which is 4 miles from Beauly, which probably accounts for the Fraser mother.
Angus and Mary McLeod arrived into New South Wales on board the
"Winifred" on 1st November 1856 with son Archibald.
Can anyone help sort this out?
