I don't know about the Blagraves you mention, but according to my records the six McLean children you list are all children of Harrison Boyd McLean, b. 1819 Maury Co., TV, d. 1862, Cedar Bayou, TX (son of Jane Blagrave and her first husband, Ephraim McLean) and his wife, Rachel Ann Smith (b. 1810 TN, d. 1897, Cedar Bayou, TX), who would be the Mrs. McLean you mention. I have "Billy's" name as William Boyd McLean. I also have five additional children for this couple: Cynthia Ann, who married James Henry George and had a son James Madison George; Mary Elizabeth; Smith; Carrol, b 1841, Cedar Bayou, TX; and Austin, b. 1846, Cedar Bayou, TX, d. June 1913, Cedar Bayou, TX. All except one of the marriages you mention are not in my records -- what is your source?
