My mother Marguerite Alice Ashton (1910-2003) was the daughter of Alice Rollason born REA (1880-1954). Alice Rea was born in Bromsgrove daughter of William Rea (1852-1928), son of (1826-1898), son of Isaac Rea (1804-1876). All of these Rea's lived in Bromsgrove.
Isaac Rea's 2nd wife was Mary (surname not yet proven), they had a daughter Harriett (born 1841) who married Thomas Henry Rea (born 1840) in 1866. They moved to Bristol in the 1870's appearing on the 1881 census in Bristol.
I know very little about the RAE family in Bristol but have been told that the surname spelling was as the result of a mistake at a marriage.
