I have still not found the relevant webpage for supposed 1998 LOVELOCK numbers in UK- perhaps someone could remind me , I missed the first posting ) But I note from 1837online that there have been 756 LOVELOCK births in the period , an average of 37.8 per year . (41 in 2003) and 723 deaths During this two decade period the average birth rate for the UK indigenous population as a whole ( excluding ethnic minorities , which have had a much higher rate ) has been about 12.5 per thousand population , and the death rate similar. Assuming LOVELOCK families conform to this pattern , then , multiplying by 80, we get a notional total all-age LOVELOCK UK population of about 3024. In my admittedly smaller HEMPSALL One name Study , the figures were : UK electoral roll (adults ) 2001 : 406 Births 1984-2003 : 131 Total all age groups 2003 about 540. If this is representative , we might apply the same ration ( roughly X 3 ) , giving a total all-age LOVELOCK population in 2003 as about 3100. This is broadly comparable with my HEMPSALL figures. As regards net migration , I cant see LOVELOCKs as more likely to emigrate than other surnames . I found my HEMPSALLs emigrants were partially offset by returnees , especially Australians. BUT: There were 1994 LOVELOCKs on the 2001 roll (the most recent reasonably complete one , before the "ex-roll" option was freely available ) Adding births, and disregarding the small numbers of deaths among under 18's to that gives roughly 2750 . I'm not sure why this figure is lower than the previous one Steve Tanner
