My 2nd Great Grandmother was Georgianna Islander Wonson, daughter of John Williams Wonson and Lydia Grandlief Story. She married William Herrick Marston. I am looking for history beyond her great grandfather Samuel Wonson 1751-1828. There is also a family story that she was the first "white woman' born on Ten Pound Island, however I have nothing to substantiate this story. Any information would be greatly appreciated. I am in Gloucester.
