Hi Carole, let us know if you find what you are looking for. I think there must be quite a demand for online accredited courses for master's degrees.
The numbers of retired people in the population of UK, USA, Canada, & Australia etc must present great opportunities for Universities, one would think, to expand their online offerings. Many retired people will want to study for personal growth and satisfaction, and I am sure many will want scholarly, accredited, and, hopefully, affordable courses.

Victorian London 'London Labour and the London Poor' by Henry Mayhew, is an excellent work packed with information. There are several volumes and they have wonderful old engravings in them. I found a couple of volumes in a 2nd hand book shop.
I haven't explored this online version, but it might be of interest:
