I have just bought indexes on CD Rom to both the 1851 and 1891 Census for Dorset. I regret K/NIBB/S are a bit thin on the ground, the only entries I have found so far are in 1851 as follows:- Name Age Born Occupation Birthplace Census Parish Piece no Jane KNIB 46 1805 Housekeeper Long Combe,Oxon Motcombe 1851 f13 Ann KNIBB 25 1826 Governess London, Mx Blandford Forum 1853 f296 James KNIBB 16 1835 Bookseller London, Mx Weymouth & 1857 f262 Melcombe No KNIBB/S in 1891 and no NIBB/S either in 1851 or 1891 I'm afraid. I may have not mastered the search strategy yet so will report if any more turn up! If you have Dorset ancestors of a different surname I will be happy to search these on request. Robin Knibb
