I am a little baffled on how to proceed with my research in order to be able to help you. Are you trying to find out Francisco Codoni/Cadoni/Codony/Codona’s descendants in Scotland?
I don’t know if you have already looked into this website which has Scotland Censuses from 1841 to 1891; Births 1564-1950 and Mariages 1561 to 1910:https://familysearch.org/search/collection/list#page=1&c...
Let me know how else I can help you. Are you searching mainly in Scotland?
