I have a Harriet Dulsibella Walker born in 1827 in Sheffield. She married Job Bullivant in 1870 in Sheffield and then went to live with him in Rotherham. I'm assuming this is her second marriage and that Walker is her first husbands surname as I can't find anyone suitable in baptismal records. Trouble is I can't find a previous marriage record or previous census records. So where was she in 1841, 1851 and 1861?
