The title page of this Family Bible contains additional information of interest:
Lineage of GRAY family, beginning with ROBERT & LYDIA GRAY, born June 2, 1761 and June 10, 1762 respectively, and married March 22, 1787.
Lineage of Gray family follows, last record being Susannah P. Gray, born August 19, 1803 and died February 8, 1872. This Bible was clearly passed down through generations as at least two and probably 3 distinct, though related, handwriting styles are apparent.
