I believe one of Henry's wives (prior to Clarissa) was perhaps named Sophia M., died 1849 and she is buried in Babcock Lake Cemetery, Grafton, Rensselaer Co., NY. Husband is listed as Henry, although he is not listed as buried there. Her age at death was 19 yrs., 10 mos., 23 days. This age would make her too young to be the mother of Sarah & Stephen Tifft, presumably Henry's children from a prior marriage OR her age was transcribed incorrectly.
Believe Henry Tifft to be the son of Barton Tifft & Hannah Miller. They are both buried at East Pittstown Methodist Cemetery.
The link below is the Rensselaer County GenWeb site that lists many cemetery transcriptions.

Good Luck.
