'Tormod [child of Jon Tormodsson and Sigrid Gunnleiksdotter] f. 1697 d. fyri [before] 1738 [married] I Liv Gregarsdotter (Epletveit 9) d. fyri [before] 1712. II Jorunn Olavsdotter.'
Since his first wife died before 1712, his birth year must be incorrect. This source also indicates that he had a son whose wife was born in 1706, so Tormod was likely born by about 1684.
