Continuing with this line, John Atkinson is listed with three wives named Merrick, Myrick, and Mirick. My attempts to merge them have been met with Unmerged Matches. While they seem definitely to refer to the same person, there are a lot of questions about their genealogies.
First the name: Robert Anderson uses the name Merrick for other families, namely John, Thomas, and William, and he does not use the other spellings at all. So I think that Merrick should be the spelling used in Wikitree.
Second, John Atkinson definitely married a woman named Sarah Mirrick on April 27, 1664 in Newbury, Essex, Massachusetts, (Family Search). Who was this Sarah? The profiles say that she was 1.) born in 1618 in Wales, the daughter of John and Dorothy Bishop Meyrick, She would have been 46 at the time of her marriage and unlikely to have had all those children. 2.) born in 1640 in Charlestown, Mass., parents unknown, and 3.) born on May 9,1643 in Charlestown, Mass., the daughter of James and Margaret Unknown Merrick. I have found that there was a Sarah Merrick born on May 9, 1643 in Springfield, Mass., but not in Charlestown. The birth date seems right, but Springfield and Newbury are 100 miles apart, a lot in 17th Century New England. Also, according to various family trees, this Sarah married a man named Hitchcock in 1667 in Springfield and moved to Connecticut.
What I would like to do is merge all three of these wives into Merrick-348 and show an unknown birth date and place and unknown parents.
