Am having a job trying to find entries for Harriet on the 1851, 1861 and 1871 censuses. I have her (married, as a Hellier) on the 1881 census, with an approximate YOB of 1849, in Freemantle, Hants. I also have the birth certificate of her eldest child in 1877, from which her maiden name has been taken; looks like it can't be anything other than Bollom to me. HELP!!!
