I don't have access to the online Grove, but will try to have a look at the nearest print copy when I can. Meanwhile, there is a short entry in The Oxford Companion to Music:

'Elizabeth Stirling. Born at Greenwich in 1819 and died in London in 1895, aged seventy-six. She was a remarkable organist, holding important posts in London and giving fine recitals which exercised much influence. At a time when Bach was little played she included much of his work in her programmes. At forty-four she married a well-known London musician less than half that age, F A Bridge.
Women hold (or should hold) her in grateful remembrance for what she did, by her example, to open to them a wider door into the musical profession, and village choral societies for her legacy to them of a charming part song, "All among the barley".'
