My husband just came across this email even though it was posted back in 2009. My husband's great grandmother was Cynthia Cook. I assume the book you are looking for is the the "Moses Perry, 1714-1801, A Founding Father of Yarmouth" written by Blanche Firth and Elizabeth Newell. Blanche passed away this past September and as far as I know, the last printing of this book was 1997. Doubt you can find another copy. However, if this is not the book you want, could you give me the name of the book you are looking for about the Perry's of Cape Negro Island? My husband would love to find another book about the Perrys. Thanks, Alice
