I remember when Townfield Lane was indeed a lane. You could walk down to roughly where the school is, then there was a lane at right angles. If you turned left, you ended up at the bottom of Holm Lane; if you turned right, you ended up where the junction of Budworth Rd./Noctorum Rd./Wethersfield Rd. now is, although back then, Wethersfield Rd. & all the houses around there didn't exist. The area was known as the Flat Lanes, if I remember correctly. Don't remember Birkenhead School owning land that far down, but we certainly had a Rugby pitch off Bidston Rd. at 53-22-57.53N 3-03-20.34W. I remember playing there.
Oh, & the Pub
near the top of Townfield Lane,(Caernarvon Arms?), next to St, Saviours was bombed during the war; 1941 I think.
