Hi Emms,
The three parts of Lincolnshire Lindsey, Kesteven and Holland were identical in function with the Ridings of Yorkshire. Prior to Local Govedrnment reorganization in 1974 they formed three County Councils, they were then abolished and replaced by one County Council for Lincolnshire,and an entirely new County Humberside was created, which embraced both banks of the estuary with a variety of local District and Borough Councils subordinate to them. There have since been further reorganizations, with Humberside County being abolished, and functions except police and fire returned to Grimsby, Hull and Scunthorpe etc. The registration district for WAinfleet was Spilsby, if I can help further please let me know.
