Jetson Family Jetson Brewster Brewster Jetson

Im looking for family members from NZ & Tasmania Aussie & England of Robert Brewster Jetson.
He was born in Laincolnshire, England on 1819 & died 1909 in North Scottsdale. Robert married Charlotte Barton & had 14 children.

We think after Charlotte he may had married her sister Martha Barton nd charged his surname from Brewster to Brewster Jetson or Jetson Brewster.
