I knew I had seen the name Snead a few times as to Bennett documents.
This is related to the death of Mary "Polly" Bennett who died in Philadelphis.
She had inherited a bounty warrant about 1834 related to her father's service in the Navy. Covington was her brother. The death date at the new LDS site is transcribed as 1839 but the original is clearly 1837.
