Indeed Myricks did exist !
You can order the History of Myricks by Gail Terry by writing to:
Berkley Historical Society Inc.
1 North Main Street
Berkley, MA 02779
It costs $21.50 plus $2.50 postage. (I have nothing to gain by sale of this book) I got a copy & it is very interesting & well written. Lots of names & indexed !!!
Hope this helps.
