This RootsWeb site (http://userdb.rootsweb.ancestry.com/intl/) is still unavailable but we’ll post an update when this changes. This site has free Sri Lanka Genealogy Records online from user-submitted transcriptions, indexes, and record compilations.
RootsWeb is now hosted by Ancestry.com and some databases have been made searchable, and still free, including:
Sri Lanka: Thowfeek Family Tree, Sri Lanka
Searches require a Surname (using at least 3 letters) and then any combination of parameters including First Name, Country, Record Type, or Year.
RootsWeb also hosts Sri Lanka Genealogy Website, with separate search engine and records.
