'Gro [child of Jon Tormodsson and Sigrid Gunnleiksdotter] f. 1689 [married] I (trulova [betrothed] 1700) Mikkel Andresson Tveit (Grå 10). II Em. [Enkemand: widower] Anstein Aadnesson Midtbøen (Grå 336).'
The second marriage appears to be an error, as it resulted in children born in 1740 and 1742. This would put Gro's birth year no earlier than about 1700, which is when she was supposedly betrothed to her first husband.
