Sarah Wheeler ye Daughter of Joseph Wheeler and Sarah his wife was born february ye 17 : 1725/6.
#S1 lists two Sarah Wheelers born to "Joseph Wheeler and Sarah his wife", one born 1725/6 and one born 1729. One belongs to Joseph Sr. and one belongs to Joseph Jr. This Sarah would conflict with Jerusha Wheeler's birth, and Jerusha is known to belong to Joseph Sr. by his will. So this Sarah must belong to Joseph Jr, leaving the Sarah b. 1729 to belong to Joseph Sr.
