IGI Batch Numbers - British Isles and North America
If the information you have found has a batch number it will be a record extracted from the original register. The letters correspond to the number of the LDS microfilm:
C = Christening records from the parish
M = Marriage records
J = Males only
K = Females only - numbers correspond to the J series for males
A batch number merely means that it is the "batch" of records which have been extracted from that particular church or chapel. A small church may only have one batch, a huge Cathedral may have many batches (but these are usually divided neatly into years).
So everyone on the same batch is an event at the same church. A different batch number for the same family just means they were at a different church or between different dates at that church.
It can be surprisingly difficult to know, from the IGI, just WHICH church you are looking at. That is where Hugh Wallis comes in. He has listed many batch numbers against their church name. For example - you find, on the IGI, baptism records for your lot. Let's say batch J073644, Aylesbury, Buckingham.
Go to Hugh Wallis Go to Buckingham(shire) page. Go to A for Aylesbury, then look down the list to find J073644. This will tell you what the name of the church was and the dates of the register entries.
