I think the parents of this profile is wrong.
The correct parents are Crispus and Mary Brewer, I believe.
The birth date is also not correct, it should be March 17 1654.

Private User & Adam Redbord as managers of this profile may not have been notified about this discussion thread so I have now tagged them in the hope that they will read this. Another action you could take Thomas is to go to 'Actions' in the Profiles and request Management of the profiles. As a manager of a profile you can edit it yourself. I would however suggest that you try to find a Primary source or alternatively a secondary source. I know you may feel that a family Association website would be reliable and it probably is but a primary source is even more reliable... if the website is reliable they probably would have cited sources.
I have started to look into this. As some of you may know, there were multiple Brewer families living in MA at the same time, with their founders all being named John. Just on Geni, there are at least 3 sets of parents shown for the Sarah Brewer who married Samuel Graves. There are several different sources cited for the parents of Sarah Brewer. I will be looking on NEGHS and at other online sites that have proved reliable when researching other conflicts in the Brewer families. However, this is my husband's birthday and we have a lot planned for the weekend, so I probably won't really get started until next week. Thanks for you patience.
Update: I have found a Sarah Brewer, daughter of Crispus and Mary Brewer born born 17 March 1654 and most likely baptized with 3 siblings 13 September or November 1659. I have also found a Sarah Brewer, born 27 March 1657, daughter of John and Mary Brewer. Samuel Graves did marry Sarah Brewer in 1677/8. However, I have not yet found any definitive "proof" of which Sarah Brewer married Samuel Graves. There are good sources for each set of parents.
I am still researching this and will post updates here. I have checked the Edmund Rice Organization, World Vital Records, NEGHS, Ancestry.com, and several family sites. If anyone has any suggestions for other sites, I would appreciate the assistance. Thanks!
