1a. Villa formed 1874, 1876

2a. Villa won the FA Cup for the first time in 1887, 13 years after their formation.
2b. Villa won the FA Cup in 1957, 13 years after the start of the second "three score and 10 years".
3a. Villa were first relegated in 1936. (8 years before end of that 70 years period).
3b. Doug Ellis handed over to Randy Lerner in 2006 (8 years before end of that 70 years period).
Another matter of interest is the fact that Villa started to become a national phenomenon in 1881, and the 1981 (last) league championship was of course the 100th anniversary of that. Not only that but 1981 signalled the end of the old era - the number of points for a win increased to 3 and sponsoring came into being. It was also the last year in which Villa were the leading domestic trophy winners.
It is also intriguing that the 1890s to 1900 was a strong decade, and so was the 1990s to 2000 decade relatively-speaking. Also that there was a 10-year gape between league championships between 1900 and 1910 and so also there was a 10-year gap in cup final appearances between 2000 and 2010.
