"The family of William and Margaret (Kennedy) Rigsbey consisted of eleven children, as follows: Mary, the widow of Frederick Shaw, of Garret (Garrard) county; Eliza, the widow of B. Conn, also of that county; Margaret, who married Benjamin Lunsford, of Garrett (Garrard) county; John William, of Macoupin county, Illinois; Parmelia, the widow of David Ross, of Garrett (Garrard) county, Kentucky; Harriet, who married James J Hawley, of Garrett (Garrard) county; David, also of that county, Lucy the wife of James Anderson, of the state of Texas; James T, of this review; and Robert H and Andrew, both of this county."

William Andrew went by the name "Andy."  He was never listed in a census as living in Chesterfield since he joined the army.

His father John William Rigsbey was listed starting in 1900.  I believe he was there as early as 1891 when he joined the Methodist church there.  He was also a member of the Modern Woodmen of America, whatever that is!  There are a lot of Rigsbey's buried in a small cemetery called Gelder Cemetery (from the His Soc Cem Bk - NE corner of the S1/2 of the NW1/4 of Section 10 in Chesterfield Twp).
