David Lee Brewer - Complete Paternal Line
The genetic line between David L. Brewer and John Brewer (m: Patience Sibley) has been verified through DNA tests submitted to Family Tree DNA on May 28, 2021, when Cathy Jean Brewer (FTDNA Test # 500336 (of an immediate male Brewer relative)) and David Lee Brewer (FTDNA Test # B667077) were determined to be a match. Both were in haplogroup "R-FTA10684" and separated by a genetic distance of 1 step. A review of their ancestry indicates both descend from this John Brewer (m. Patience Sibley). Specifically, John Brewer's (m: Patience Sibley) son, John B. Brewer (sometimes referred to as John A.L. Brewer (which appears to actually be a conflagration of other similar family names at the time, more specifically, "Adolphus Lanier" could be the basis of the misappropriation of the initials "A.L." to John B. Brewer).
