Charles Johnson McNeill was AMW's brother. He married Elizabeth Coffee (or Coffey), of St Augustine, E. Florida and had nine children: Donald C. (1844-1876), lived as a boy with AMW in Philadelphia (her 'adopted son'); Joshua S.; Charles W. (b. 1847), m. Fanny Stevenson; Ellen M. McNeill, called 'Tante'; Alvan C. (1852-c.1943), m. Louisa Christenson; William Palmer (1857-1947), m. Nealie McNeal; Anna Alicia (1858-1950), m. Alvan Van Buskirk; Peral E. (1860-c.1878); James Bolton (b. 1860)
Inherited land, Beauclerk's (now Beauclerc) Bluff, south of Jacksonville, Florida, on the west bank of the St Johns River, from his uncle Zephaniah Kingsley. Lived at Reddy's (now Reddie) Point, formerly also known as the 'Atkinson and Richard Grants', on the St Johns River, Florida, where AMW visited him in March 1858, #06495. The signature on two letters concerning surveys of Reddy's Point, 1851 and 1853, however, reads 'Chas J MacNeill' (Spirer Collection); and 'Charles J Macneill' is named as one of the beneficiaries of Alicia McNeill's will in 1863, #06677.
