TAY, Martha, d. of William and Susanna, [born] Feb. 4, 1758.
It is not clear if the two births of Martha Tay, one year less 2 days apart, are meant to be the same event. No death date for the first one is found. It does not help that the age at death of the "survivor", 73, calculates to a birth in 1758, unless it means in her 73rd year, in which case it might mean 1759.
