Those researching descendants of John, William and Charles Merriman (born late 1600s) might find information they are seeking in the 2005 edition of a book about early families in Maryland. The book has a chapter on the Merriman family which settled in Virginia, then Baltimore and Harford Counties, Maryland. Nicholas Merriman was also a common name among Merryman descendants.
The book is about the Glenn, Merriman, Day, Slade, Gorsuch, and Rutledge families in the 1700s and early 1800s. One feature of the book is that it shows marriage relationships among the families. Someone descended from one of these families may be descended from others of these families due to marriages back in the 1600s and early 1700s.
