This is so frustrating - found Philpot St once before - never to be seen again.
BUT went back to last posting on that elusive street and noted that it came under St Andrews Terrace (which it doesn't this time I looked) but never mind right next door to St Andrews terrace is
Pear Tree St, St Mary Lambeth
Henry Chamberlain, 40 labourer born London
Mary 45, born out of London.
and the reference is
HO107 1061 ED 4 folio 34.
