Hello Di
This area is a little difficult to get address information for, or even narrow down the parish.
Endell Street baptisms originally appeared in St Giles In The Fields & St Andrews Holborn before I think 1752, so that gives an idea of the area covered, St George Bloomsbury would likely also be included.
This is an entry, perhaps for the previous generation of the family at St Giles In The Fields
Baptism 24 Dec 1753 Child's name: Francis. Father's name: Adam
Mother's name: Sarah Father's surname: SOMMERVILL
Line transcript: Francis of Adam and Sarah Sommervill
Probably not much use, but the next source I suggest is the rate books for these parishes. The rate books contain the name of the head of the household & will give you the address of the family year by year if they paid one or more of the various rates (e.g. Watch rate, which paid for the Watch, a forerunner of the police). The rate books are parish records, so if they still exist they're likely in the "parish chest" at St Giles In The Fields, for other parishes they may be at either LMA or one if the local libraries (look under Camden Libraries & enquire). There is a lot of information if you know where to look, it's just finding these records that takes all the time.
