I can't tell what type of record this batch is (MSPX-2L3). Is there any way of finding out?
It is the Book of Baptisms. Here is a link to the film. On Image 471 you see Day Book of Baptisms and the image in question is Image 588. The first column is labelled Born on the fourth page of the book. (Image 482) So those birthdates.
Most of the newer babies in my family have 3 given names. It wasn't uncommon to have 3 given names in the 1800's and is regaining popularity.
Have you looked at the previous reference images to see if there is a heading? You can always return the Batch as well.
I do agree with genthusiast, that they do look like a birth record.
Anyone else working on "UK, England, Middlesex—Parish Registers, 1539–1988 [Part B]" that could help Emily out?
