Whoever she was, she might also be the Ancellexia, widow of Petrus Bovet, who made a "reconnaissance" for property subject to the Priory of Lutry about 1503 (ACV Ff 34, fol. 11, terrier compiled by Pierre Marchand, not yet examined).
Given name is written clearly "ancellina relicta quondam Johannes pignyollet de chessard" and "ancillesca relicta quondam Johannes pigniollet de chessard" in two notations in the record book of Nicod Méan of Payerne, 1502 and 1507 (appears to be
acknowledgement of debts, 3 sacs of meal and 7 livres lausannois). Another document involves "Girardus filius quondam Johannes pigniollet de chesat". (Another researcher reports "Annelisa", clearly an anachronism.)
1900 census shows son by prior marriage (i.e., step-son) Andrew M. Rowley, b. ??dec1888. (Also 1910 census, ED 24, p. 344)
Son Andrew M. Rowley was born in December 1888, and son Lawrence G. Barnett was born in January 1892. However, the latter is listed out of order on the census, could belong elsewhere though still listed as "son".
