regarding an indexing issue
I am currently reviewing a Baptism register for the year 1801 for Middlesex UK.
The register is set out as if written in an exercise book with the date of baptism in the left column, the name details in the centre , and birth month and day in the right column.
On three of four listed entries, a second year 1800 appears above the name of the person in the centre column with the day and month in the birth date column.
The fourth entry adds yet a third year to the equation by including a birth year of 1798 in the birth date column as well as the 1800 above the name.
The original indexer used 1801 as the date of both baptism and birth except for the last example above.
As the dates of the baptism register run in date order, I am wondering if the additional date of 1800 in three of the four examples was the birth date, or should the date of the register 1801 be used for both baptism and birth. I'm unable to find any reference about this situation in the notes.
Your assistance with this issue would be appreciated.
