Its original founder members were:

The Sealed Knot made eight attempts between 1652 and 1659 to bring about the Restoration.
The biggest revolt was staged in 1655 and is known as the Penruddock uprising, named after one of the leaders of the revolt, John Penruddock. The revolt was easily put down by forces loyal to the Lord Protector Oliver Cromwell, and for his part in the rebellion Penruddock was beheaded in May 1655.
