Hi Bary Your friend might have to take into consideration that there was only one child born to this family, then again there are a number of other Richard & Hannah/Ann Parker families scattered around England during that time frame on the IGI, which if the family moved (Staffordshire for example), could belong. The census data 1841-51 etc. will be the only way of tackling this problem, though perhaps even that data could be a little too late in time. Even so, way to go perhaps! Cheers Graham Melbourne
