On Ancestry, put in Charlie Albert Brewster and start working backwards, picking up hints from other trees if you don't have Intl. Ancestry. I have traced back to 3 Mayflower Direct Line Passengers on Ancestry. I joined the Mayflower Society in Sept., 2013 under William Badford. I had a genealogy book with all info, lines, & documentation in it. Cost me $500.00I paid a genealogist with DAR to document all for Mayflower Society and she charges same price for anyone. but you've got to have some sort of a line started for her to work with.Remember, on Ancestry, you can only go back in time, not forward. There are many Brewster genealogy CDs on E-bay to buy, too.I have been working on a fellow mayflower member's Brewster line on ancestry. Many were from New York, Scarsdale & Westchester area. And Long island. Contact me if you want.
