A good internet source is https://familysearch.org/search
You enter person's names and dates and location, and click on search. It's a free service, and has worldwide records.
(Familysearch.org is especially good for Scotland's records and you avoid paying credit fees that www.Scotlandspeople.org
charges. The latter keeps their records hidden so you'll pay directly to them to see their records).
