Martha Emmons (Cooley) - if Martha died when she was 13 how did she have 3 kids?

Hi Diane, that makes perfect sense; however, which record are you talking about? I assume you are Martha Cooley (b. March 28, 1650 - d. about 1708)?

Is this the profile you are referencing?

Martha Emmons

On a gee whiz note: about one in 8,100 natural pregnancies results in triplets. REFERENCE: https://en.wikipedia.org/wiki/List_of_triplets

Also as sad as it is the youngest age known of a girl getting pregnant is 5 years old.
