Sarah Wheeler ye Daughter of Joseph Wheeler and Sarah his Wife was born April 7 : 1729.
↑#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" (not the son of Joseph Sr). The Sarah of this page has no 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 Sr, leaving the Sarah b. 1725/6 to belong to Joseph Jr. This is confirmed by the guardian bond dated 7 Mar 1735/6 which says Sarah, d/o Joseph Sr., was in her seventh year, so born about 1729.
