Daniel Searles and Caroline Burgess married on 15/1/1850 at St John's Church, Adelaide.No ages or father's names were given for either person.
There is a Caroline Searle who married William Charles Christian Bornholm on 16/7/1878 at St George's Chapel, Stepney.She gave her age as 21 and her father was Daniel Searle and he gave his age as 27 and his father as John Frederic Bornholm.
Hope all this info helps.I can do Birth Lookups to 1906 and Marriage Lookups to 1916 in South Australia.Unfortunately I don't have the Deaths CD.
