Ok, like everyone I have eagerly awaited this as I hoped it would help me. Not yet, it seems

so I am looking for some pointers on how best to search before I make myself bankrupt with the cost

The info I have is as follows
1901 Census - Eynseford, Kent
Mary Jane Hill, Head, b 1843 Canada
Sarah Ann Adams, daughter, b 1874 Lancashire
William Robert Adams, grandson, b 1898 Wandsworth
Along with Sarah's sister Florence Hill & brothers William Hill & James Hill.
Sarah then moved about as she had her children
Pretoria May Hill, b 02/07/1901, 3 Best Cottages, Crockenhill, Kent
Annie Elizabeth Pearce Adams, b 09/12/1903, 3 Tylers Hill, Crockenhill, Kent
Frederick Charles Donald Adams, b 26/01/1906, 7 Alexander terrace, Swanley, Kent
There is then a gap until another 2 daughters
Maude Evans Adams, b 12/02/1912, 37 West Hill, Dartford
Emily Adams, b c1913 (not found her birth yet) d 1915 Dartford workhouse.
In 1914/1915 Sarah & some of the children are in the dartford workhouse, where Sarah dies, so I am assuming they stayed around the Kent area.
I have looked at Alexander Terrace and West Hill but can't seem to find any of them as either Adams or Hill (Sarah used whichever name she felt like).
So, can anybody give me some advice on how to try and find this family in 1911. Are these addresses all in the same area of Kent so I could just put one place in, or am I destined to spend a furtune searching?
All advice gratefully received (by my bank balance especially

)
Thanks
