I hope it is correct to accept "Colonial Settlers of Prince George's Co., MD".which shows twins James and John b. 16 Feb 1756 among the children of James and Susannah Downing (KPG p. 312) on p. 102. Also - it bothers me that they had a son Joseph, is apparently not accepted by all researchers. What is your opinion on Joseph? He is my line. Thanks,Mary Lou, for your research and time. Marlene >
