The father was Hans Torstensson. The mother was Maria Bengtsdotter. The child was Kierstin here, but this was long before the time when there was one and only one correct spelling of a name. You will likely find other spellings of her name in different records. Writers spelled the way they thought a name should be spelled, and they might decide to spell the name differently at a different time or even in the same record.
The child was baptised 22 post Trinitatis (22nd Sunday after Trinity) which in 1716 would have been 28 October 1716.
