Trish,
That's the right family listed on the "Marion Moore" although Thomas (13) & Alexander (11) were actually McMillans (from the first marriage of Agnes, 39) and my g grandmother (Agnes Ann Duggan 1852-93) was listed as "Angus (1)". Others in the extended family on the "Marion Moore" passenger list were the older McMillans, Hamilton (wife & daughter), John & wife, James & Nathaniel. Only Hamilton & John & their families sailed on the "Marion Moore" though. The McCances & the four younger McMillans sailed later on the "Confiance" which was quarantined at the heads on arrival at Port Phillip. I don't know what happened to gg granny's left arm though and why she fudged her age down and John (1819-1907) fudged his up, perhaps she felt guilty about being a cradle snatcher!
