Walter Aston, 2nd Lord Aston of Forfar was the second and eldest surviving son of Walter Aston, 1st Lord Aston of Forfar, and Gertrude Sadleir, daughter of Sir Thomas Sadleir of Standon, Hertfordshire, and his second wife Gertrude Markham. In 1639, he succeeded his father as Lord Aston of Forfar in the peerage of Scotland, and, in 1660, at the death of his maternal uncle Ralph Sadleir, he inherited the lordship of Standon and other estates in Hertfordshire, England. His principal seat was Tixall in Staffordshire. Lord Aston was a staunch Royalist during the English Civil War. He was present at the Siege of Lichfield in 1643 and the surrender of Oxford; King Charles I expressed his regret at not being able to reward him as he deserved. After the failure of the Royalist cause he was required to compound for his estates and live in private. He married in 1629 Lady Mary Weston, daughter of Richard Weston, 1st Earl of Portland, Lord High Treasurer of England, and his first wife Elizabeth Pyncheon. He was an ardent Roman Catholic and was the effective leader of the large Catholic community in Staffordshire, although he was unwilling to profess his faith publicly. When he was charged with recusancy in 1675 he wrote indignantly to the Secretary of State that "he never went to Mass or joined in any worship particular to the Church of Rome ". No further action was taken against him. "The munificent Lord Aston" was extremely popular locally, and a thousand mourners are said to have attended his funeral: it is notable that no attempt was made to conceal the celebration of Catholic rites at the funeral, even though many of the mourners must have been Protestants. He died on 23 April 1678, and was succeeded by his eldest son Walter Aston, 3rd Lord Aston of Forfar, who inherited his father's role as protector of the Staffordshire Catholic community, and narrowly avoided becoming one of the martyrs of the Popish Plot. He was buried at St. Mary's Church, Stafford. His widow did not long survive him: according to her son-in-law Sir John Southcote, "she grew melancholy and lost her wits, keeping almost perpetual silence and refusing nourishment." They had at least two other daughters, Frances, who married Sir Edward Gage, 1st Baronet, and Anne, who married Henry Somerset.
