"Major LeGrand GUERRY, the great, great grandson of the Emigrant [1.], married Sarah CAPERS, the sister of Bishop William CAPERS, of the Methodist Episcopal Church, South, whose son, Ellison, became the Seventh Bishop of South Carolina [2.], and my father's [3.] predecessor in office [4.].  Therefore, William Capers GUERRY, the son of Major LeGrand GUERRY and his wife Sarah CAPERS, and the Rt. Rev. Ellison CAPERS were first cousins.  The father of Sarah CAPERS was Capt. William CAPERS, whose biography can be found in The S. C. Historical and Genealogical Magazine Vol. II, p. 273."
