Not sure if you subscribe to Ancestry but there are a number of trees there suggesting that Isaac Bradburn married Catherine/Christiana Jarratt in 1811 but no source given.
Have found the following marriage in the Shropshire marriage index
6 July 1811 Broseley Isaac Bradbon and Christiana Jarrett

Thanks for the information
Looks like we are related through Thomas Bradburn. Thomas had a son John (first marriage) , who married a Barrhead girl and started my mothers family tree
