Hi Norberto,
That is good news, it will be good to see it, although, you may have to amend your tree, due to age difference etc.
I have seen an Archibald and Mary Sives family in 1861 census in Staffordshire, England, but young Archibald is shown as 5, so born in 1855 probably. So that is 10 years out, and he was born in England although his father, Archibald was Scottish.
