Robert Redhead B About 1829 Ancestors and Family from First Marriage IN Northumberland

Researching the Readhead Redheads from the Rothbury area in Northumberland, specifically looking for information on Thomas Readhead m Jane Bell and the descendants, if any, of their first son Robert Redhead - Readhead b about 1829, and his daughter Sarah b 1850 to Jane Readhead nee Carmichael in Northumberland. My research leads me to Robert Redhead convict 3401 sent to WA on the convict ship Stag in 1855, who later married and became Robert Readhead a successful pastoralist in the Greenough area.
