Thanks guys
Yes, the Church near Regent's Park is the one near to where this family lived. The Bermondsey Church makes a big thing of how 'Magdalen' is spelt (not Magdalene) and since the name is spelt the same on both these Churches I thought there might be a link. Perhaps through the school ?
I did wonder if there had been a mix-up in attributing these Baptisms, but the original Register very clearly identifies the Bermondsey Church at the top of each page.
