I have found that the British Elsie Hamilton, active in 1930s, married H.R. Phillips, but in Wimbledon's draw 1947 there are Elsie Hamilton and Elsie Phillips, both defeated in 2R. Also official website writes that: http://www.wimbledon.com/en_GB/score...7/LS/r2s1.html
A tournament shows us a continuity line between Elsie Hamilton and Mrs H.R. Phillips: in Budleigh Salterton, Hamilton was RU in 1938, Mrs H.R. Phillips was RU in 1948 and divided the prizes in 1951.
So we can suppose that marriage is right (confirmed by Wimbledon website) but we would must suppose another Elsie Phillips too and a Wimbledon website's mistake about her.
