I do not have the records in possession at this time, I will have to obtain them from my mother. The sources e.i. Rowley V.R. & Boston marriages, are in ref. to the marraiges of the three brothers. The connection showing them as brothers was found in emigration, and property records, which I believe are in the possession of the genelogist working on our family history. At present he is working on finding out who their parents were, and were in England they originated from. I would be more then happy to provide you with copies of the records in questions, as soon as I can obtain them from my mother. In the mean time, here are the marriage dates of Luke and William. Luke married Abigail Hammond 30, Jan 1689, one child is known Abigail born 17, Sept. 1690, Boston, Suffolf, Mass. William married Elizabeth Mather 23, June, 1696.
As with you, there is a ton of unconfirmed info out there, and I believe if someone is taking the time to do their family genealogy they should not take the word of some stranger they met on the web. Sometimes leads pan out to be true, sometimes they don't, they always need to be backed up.
I am dedicated to doing my family history, if I allow information to be added to my history that is not confirmed, than I might as well make up my own names and dates, and call it quits.
