Some pages in this book on Yeamans family mostly on John Yeamans who went to Barbados and was created a Baronet 12th Jan 1664. Book refers to his brother Robert Yeamans created a Baronet Dec 31st 1666. As far as I can pick out from this account Sir John Yeamans who went to Barbados had only one son by his first wife, his successor to the Baronetage Sir William Yeamans who married Willoughby Brown the daughter of Sir James Brown and they had only one son Sir John Yeamans who married Ann Scantlebury and at the time the book was written this couple also had a son John Yeamans and this heir to the Baronetage was living in 1740. I am thinking that the Sir John Yeamans who married Ann Scantlebury could have had a sister Willoughby Yeamans (their mother was Willoughby Brown). It seems there was Sir John, then Sir William and then 2 more Sir John's in a direct line. Regarding Sir John's 1st's second wife Margaret Forster, daughter of Rev John Forster of Barbados. (He doesn't go into her 1st marriage to Berringer). You can find the above book on-line. Several of Sir John 1sts daughters are mentioned and a son Robert Yeamans by his second wife Margaret, this son Robert married Elizabeth Mellows and they had 3 sons, 2 of them living when this book was written.You can find a copy of this book free on-line.
