I am trying to trace William Rolfe, b 1831 England. He was sent to Western Australia as a convict in 1851 where he married Mary Ann Ayres in 1853. His conviction was in Chelmsford, possibly he was born in that area. Does anyone have any information on his or Mary Ann's birth, death or parents?

William Rolfe and Mary Ann Ayres have 3 Children,1 Mary ann Rolfe,2 William winson rolfe,3 George Rolfe,4 Rebecca Rolfe.As my mother that her mother is a Ladhamsthey changed there name to Mary then marred Gerge Ladham as I am still working on it.dinarechichi@westnet.com.au
P.S Mary annAyers was born on the 30 July 1838 and death on the 26 Aug 1923 and I do have copy of certify.
