I'm a little confused, Jodi. The only thing shown in her profile is her first name, the connection to her husband and a daughter, an estimated birth date of 1700, and a link to a page from "Concord, Massachusetts, births, marriages, and deaths, 1635-1850". The page only has 1 person with first name Martha on it, whose last name was Adams and she was born in 1724.
Your source is a link to the title page of the same document, which does not have any information about anyone.
Even if you change the link to point to a page that shows the birth record for someone named Martha Brabrook, I don't see how you can make the connection between that and someone named Martha who married Abraham Estabrook on an unknown date and place and had a daughter with him.
