SOURCE:"The Mark Family"compiled by lt. Col.Edward E. Sampson. William Mark died in Kentucky in May, 1833 and his will dated 12-24-1832 was probated 8-6-1833. Sarah is believed to have died in 1865. Their known children were:(1)John Wesley who married Elizabeth Detro (2)Miles (3)Elijah (4)Anna who married John Wallingford (5)Rebecca (6)Sarah (7)Rebecca (8)Amelia (9)Thomas Fletcher (10)Timothy whose daughter married Samuel A. Wallingford (11)Titus (12)Silas (13)Louisa (14)Matthew and (15)Ransom L. I hope this helps. I have nothing further back or on Sarah Schofield's line at all. If you want to pursue the Wallingford line you can go to "The Wallingford Exchange" on the net. Good Luck.
