[Note: transcription of will of father given, dated 1730, mentions daughter Lydia between daughter Mary Safford, and grandson John followed by daughter Elizabeth. The source cites the recorded will which contains a blank after Lydia but the transcription did not capture the blank space. Source:Holman, Mary Lovering. Ancestry of Charles Stinson Pillsbury and John Sargent Pillsbury has an abstract giving the name as Lydia Blea, which is based on the original will in the probate file here.]
