We know that Frances Ethel Ringland and her two daughters, Aileen Dora and Effie Lyndall, were at Woodcote on 2 April 1911 (when the 1911 census was taken) but we don't know when they arrived or when they left. They were in Wandsworth in 1901 census.
I've been looking through newspapers and have found articles relating to Mrs. Ringland, Miss Effie Ringland and Miss Dora Ringland in Dymchurch (though no specific mention of Woodcote). The earliest article is in 1907 and the latest in 1915. The articles themselves don't give many clues, they are mostly reports of local musical plays and social/fund raising events in the village, Effie acted in plays, Mrs. Ringland played piano/organ.
There are also some advertisements by (Aileen) Dora Ringland selling puppies, and on some she puts her address as NONSUCH, Dymchurch (1910, 1912, 1913) If you look at the original image of the 1911 the name Woodcote is crossed through and just visible is another word underneath - could that be Nonsuch? Woodcote is written again below.
I have also found a 1913 Area Directory record for Mrs. Ringland, Nonsuch, Sycamore Gardens, Dymchurch. I have browsed though Sycamore Gardens in 1911 and there is no other house called Nonsuch. So it appears the house may have changed its name at some point.
Just to confuse things, there is an article referring Mr. J H Cooper of Nonsuch in 1910 and also a Miss Fisk of Nonsuch in 1917.
Then I found the article below in the Folkestone, Hythe, Sandgate & Cheriton Herald 31 March 1917.
Effie married in 1916 and Aileen in 1918, so they would have moved on by then.
I'm not sure if this will help in any way.
