From the publication "Iams of America" Landed Gentry of Maryland, First Edition Copyright 1998 by Ralph D. Reynolds, M.D. page 21. Richard Iiams (b.February 15, 1749; married Eleanor Musgrove). Richard the son of Thomas Iiams (b. August 7, 1708 Anne Arundel County, Maryland. Thomas listed as fifth child of William Iiams (b. 1670 and Elizabeth Plummer; married a woman whose first name was Artridge.Thomas Iiams and Artridge had nine children: Elisabeth (b.1732), Sarah (b. 1734), Artride (b.1736), Charity (b. 1739), Susanna (b. 1742), Thomas (b. 1745), John (b. 1747), Richard (b. 1749) and Mary (b. 1752). There are many lines of Thomas, Richard, and William Iiams, Iams, Iames, Ijams and on it goes.It becomes very difficult to sort it all out.Several genealogist have committed a great amount of time researching the Iiams family tree.Most have given it up and little has been published.Hope this is helpful to your efforts.
