But it did change to Wallasey in 1928 The books Moreton Wirral a Pictorial History by Frank Biddle and Alan Fellowes there are 4 in the series has some pictures of Kerrs field .I went to the library to few them after Cassandra emailed me Reading some of the captions people where allowed there after WW1 as there was a shortage of houses they built there own houses on stilts or old railway carriages it was known as "Shanty Town" at one point there where thousands living there.they lived there up to the 60's Hope this helps you Sylvia (Wirral)
