Football may be older than we think. Evidence uncovered at NLS has suggested that Scots nobles were playing with 'fut ballis' back in the 15th century!
FOOTBALL, n. Sc. usage: a sum of money paid by a married entrant member of a merchant guild on behalf of his wife to allow her to share in the benefits of the common fund. For the orig. of the metaphor see Ba-siller, Ba-money.
*Per. 1830 Perthshire Adv. (2 Dec.):
If the widow be poor, has she not a right to the funds? or why does her husband pay what is called a foot-ball? is not this regarded as his wife’s entry-money?
