I have hit a brick wall on two families, as follows:
JOSIAH ROBERTS and his wife, LUCY ROWLETT. Josiah (b. 7/23/1802, d. 5/11/1863). I do not know where he was born, but know he was married to Lucy Rowlett in Chesterfield Co., VA. He died and was buried in Dundas, Lunenburg Co., Virginia. Facts are the same for his wife, Lucy Rowlett, who was b. 3/4/1812, and d. 5/27/1882. I visited the Lunenburg courthouse and reviewed records there, but found nothing for Josiah or Lucy. I cannot locate their parents' names.
JEREMIAH TAYLOR and his wife MARY EATON. Jeremiah was born 11/5/1755 somewhere in VA, and died 11/8/1806, also in VA. His wife, Mary, was born 3/10/1745 and died 10/12/1789 - do not know where she was born or died.
