He was the son of Henry Everard, a gentleman who suffered imprisonment for the Catholic faith, and of his wife, Catherine Gawdyr.
Becoming acquainted with Father John Gerard he made the spiritual exercises with him in London.
He studied philosophy and divinity at Rheims and Courtray, and was ordained priest 18 September 1592.
For several years he was minister at the college of St. Omer and at Watten, and socius and master of novices at Louvain.
On endeavouring to return from exile in July 1623 he was seized at the port of Dover, but was eventually released on bail with the loss of his "books, pictures, and other impertinences".
