I found this YouTube video submitted by Find My Past. It features John Hanson from the Society of Genealogists whom I heard give a really interesting lecture at the WDYTYA Live, at Olympia in February.
In it he explains why we should be wary of not distinguishing the difference between a memorial and a burial record.
The difference, it would seem, is that with a memorial the inscription refers to ancestors who are possibly buried in the grave, but not necessarily as their names may have been added to a family memorial while they can be actually buried elsewhere. Burial records, on the other hand, give you information of who is in the grave, but here you may find that although the deceased is buried in the grave, they may or may not be on a memorial!
Find my Past has Parish records from when they were officially collected in1538 onwards and also even has some from the 12th century! The database of transcripts, that they allow you to search, is one largest on line and has been compiled with the help of the Federation of Family History Societies members. You won’t find them anywhere else on line.
Here’s another on Other Specialist Records.
Got any military records that you want to find? This may be of help!
