Ayloffe’s great-grandfather bought the manor of Brittains in 1501 and was granted arms in 1512.
In July 1619 Ayloffe joined with his kinsman Sir Anthony Thomas in a proposal to drain the fens in Northamptonshire, Huntingdonshire, Cambridgeshire, Norfolk, Suffolk, Lincolnshire and Ely at their own expense, in return for a proportion of the increased profits of the lands. The king gave permission for the undertaking, but the local sewer commissioners proved obstructive. Terms were agreed before the Privy Council, but by September 1620 nothing had been done. The projectors protested that they had ‘ridden 10,000 miles and spent £2,400 and yet find the country averse to their undertaking and plotting to compel them to desist’, and petitioned for their cause to be referred to the forthcoming Parliament.
In his maiden speech on 3 Mar. 1621, Ayloffe moved that William Man* should make a private search for the monopolist Sir Giles Mompesson* and his papers.
The failure of the drainage scheme left Ayloffe with mounting debts he could not repay. By 1624 he was driven to ‘conceal and hide himself’ from his creditors, and a year later he had been outlawed for debt.
