There is a gap between the June 1661 and Nov 1664 baptisms where another child was possibly born to Abraham and Sarah Grimshaw.
There is also Edward Grimshaw from Rawden who died 1737, aged 70. Also, it is believed that the Grimshaw families from these parts are all descended from the one common ancestor, Edward Grimshaw.  A birth early 1662, midway between these other births is consistent with Edward being 70 when he died.
