Have just read this post.
Do you have details on this Catherine Adamson?
My gt grandmother was named Catherine Adamson - that was her married name. She was born Catherine Wilson in Aberdeen in 1827.
She was married in 1846 to Mark Adamson in Aberdeen and they had 2 children. Mark (supposedly) drowned around sometime after the 1851 census, and Catherine remarried in 1855 to my gt gt grandfather John Thompson.
Catherine had 1 more son, and in 1859 the family emigrated to NZ.
In 1860 they left NZ and went to Australia, but returned to NZ in 1861. John Thompson drowned on the voyage back to NZ.
The dates do not fit your dates but my Catherine Adamson was in Australia briefly in 1860-61.
Oh yes, and I do know of one descendent of Catherine Adamson who currently lives in Australia (I think Sydney) - although she was actually born in NZ.
