Indexed batch name not correct or incomplete
Batch Name of Indexed Records: “Massachusetts Deaths, 1841-1915, 1921-1924”
The Birth Record for all four siblings in this family were included in the same batch, which indicates by batch name they are only deaths records.
I did edit the Batch title of each individual source, after they were attached in the Sources Tab of each Person Page on my family ancestors, but I suggest that the batch name should include both “Births and Deaths” to eliminate confusion. I am including this image for your review.
