John Lewis Pasteur (II) was the second JLP in the family tree and the only one I know anything about. He lived in Melbourne and was described as a hosier (1). He died quite young at the age of 28 in 1782.
He married by licence Anna Maria Clifford who was the illegitimate daughter of Margaret Clifford and Laurence, 4th. Earl Ferrers of Staunton Harold. Margaret had four daughters by the Earl and Anna Maria was the second daughter born in 1745. The Earl’s marriage to Mary Meredith was a failure and he continued to cohabit with Margaret Clifford. Ferrers was a man of irascible temper and one day, in an argument with his agent, John Johnson, he shot and killed him. The Earl was tried by his Peers in the House of Lords, was found guilty of murder and was hanged. The children were able to visit their father when he was in prison. Earl Ferrers left £500 in his will to each of his natural daughters. [Howard Usher – personal communication & “Kirkland Papers, 1753-1869” A. Crane, Crane Press 1990]
There are two memorials to the Pasteurs in St Michael with St Mary, Melbourne (pictured on the right). There is a flagstone in the south aisle which reads:
In memory of Mary Pasteur, daughter of Mr. John and Mrs. Elizabeth Pasteur. She departed this life, 25th. day of August, 1767.
And inside the church there is a memorial plaque which reads:
THE MEMORY OF JOHN LEWIS PASTEUR WHO DEPARTED THIS LIFE AUGUST 2ND 1782 AGED 28 YEARS
ALSO OF ANNA MARIA, WIDOW OF THE LATE JOHN LEWIS PASTEUR WHO DEPARTED THIS LIFE JANUARY 26TH 1819 AGED 73 YEARS
