1738 AD imprisoned
From Alexander Cruden – Madness or Affliction?:
Being desperate for money [to print his Concordance], he attempted to marry a rich widow from church. Unfortunately, a rival suitor, a Robert Wrightman found out about Cruden’s previous imprisonment and had him thrown into Matthew Wright’s private mad-house in Bethnal Green. He was 39 years old.
Christian friends and ministers from all around supported Cruden and he managed to escape after spending 70 days in the asylum whereupon he sought to sue Wrightman and Monro.
