To locate family members who went to live abroad there are several websites that could help.
"ellisislandrecords.org" and "castlegarden.org" have records of immigrants into New York and "italiangen.org"
has New York marriages and deaths. You can also search the U.S. social security death index on "ancestry.co.uk"
and the 1920 and 1930 US censuses if you subscribe to a World deluxe membership. The provinces of British Columbia,
Manitoba and New Brunswick in Canada have online searchable databases of births, deaths and marriages as do the
states of New South Wales and Victoria in Australia.
