I'm seeking info on the family of William Leonard Duvall of VA or MD.He married Comfort Cole on 9/27/1831.They had 10 children.Rachel Ann (9/3/1832-3/12/1925), Mary Emma (11/8/1833-?), James Nicholas (4/12/1835-?), William Leonard (11/5/1836-?), Sarah Elizabeth (5/24/1838-?), George Washington (4/19/1840-?), John Prussia (?)(2/14/1842-?), Altagena (10/2/1843-?), Comfort Elbertina (my great-great grandmother)(2/20/1853-?), and Arthur N. (8/1/1848-?). A distant relative informed me that they lived in Anne Arundel Co., MD, but new sources indicate Orange Co., VA.Also I was informed that William Leonard Duvall had something to do with the Orange & Alexandria Railroad before the Civil War.George W. and John P. are listed as serving in Co. C, 13th VA INF from Orange Co., with George listed as serving with the railroad in 1861-1862.
