Terressa and her husband William Erskine Bridges were divorced in February 1848. He came to Utah with his wife Margaret Robison Bridges and his second son, Worthy Franklin Bridges, in 1851. Terressa brought her son Robert Albert Bridges with her. Further research is needed to determine the name of the pioneer company with which they traveled.
The 1850 Utah census shows his name as "Robert Chamberlin." His mother Terresa was married to Solomon Chamberlain.
