Three of my gg-grandfather's siblings married Crews. A Crews brother and sister and their Crews uncle. I have followed these families reasonably well through census records but that only takes me up to 1930. I would be delighted to hear from my cousins who descend from these marriages.
James Crews m. 1805 (Barren Co., KY) to Nancy Monroe
Nancy Crews m. 1820 (Wayne Co., IL) to David Monroe
Peter Crews m. 1824 (Barren Co., KY) to Martha "Patsy" Monroe
Nancy and Peter Crews (b. TN) are children of Andrew Crews and Ritter Bradley
James Crews (b. VA) is brother to Andrew Crews
The father of Andrew Crews and James Crews is said to be Peter Crews..
The Monroe siblings are children of Johnson Monroe m. 1871 Amelia Hooper in Lunenberg Co., VA. The Crews and Monroes knew each other in Lunenberg Co., VA (deed records).
