Hi Diana

Let me have your email via the user name profile I am tonyjenkins.

The link to Iron and tin fits with the demise of tin manufacture at Redbrooke the family moved into stone cutting quarry owners.

I am not sure about the link to William/Elizabeth Prichard I am researching a link to William Jenkins of Mellingriffith (West Cardiff)

I believe Richard could have moved to Tredegar re existing family. I believe he had a Uncle (John) living close to Llandaff.

I believe the link to tin/iron is through the Coster and Vaughan families

I believe Anne the sister of your Richard died as a spinster in 1806.

I have not been able to trace

1. Jane b 1773
2. William b 1780
3. John b 1787
4. Eleanor b 1796

I look forward to hearing from you.

Regards

Tony
