I have never really considered much that Lucy Broadwood, Annie Gilchrist, Mary Neal, etc., were any different to the male collectors as far as collecting goes.
.... and neither have I, or at least in the years that I have heard all these names, It was many years after I heard Cecil Sharp's name that I heard that of the great achievements of Mary Neal and I am sure some earlier writers did not give her the credit she deserved - especially after she fell out with Sharp. Was Maud given all the credit she deserved at the time or has that only come later? In particular, I am thinking of Georgina Boyes' article The Lady That Is With You.... Maud Karpeles (1885 - 1976) in Step Change Ed. Boyes. (Francis Boutle (2001) and in various places in her better-known The Imagined Village. There are other examples. The neglect of the historical contributions of women is having to be reassessed in a wide range of disciplines.
You ask how relevant it is here. I was contrasting the approach of Steve Roud with those who bring a already developed socio-political agenda to their writings. I was trying to categorise them and stating that one that had gained most credence was the one that argued that the contribution of women had not been fully recognised.
