OK, here's one to start off this forum, going right back to the early days.
AJ Baker was a prominent player in the 1860s and early 1870s, he played for NNs of Kilburn and Wanderers. Also a good athlete, he won the 100 yards championship in 1870. Has anyone confirmed his identity?
I am on the track of an Alfred Joseph Baker, born 1846, brought up in Kilburn, ran a prosperous business, sent a son to Harrow, died 1900 - so he ticks the boxes for age, location and social class. But I have yet to make a direct link between him and the footballer.
