A few more references (which probably aren't all correct) for the Charles John Jenkins Thomas Donne that others have posted about. I'll include the references already posted just to make things easier to follow.
John, the father of this Charles, had various occupations: police officer (1851), national school master (1861) and and accountant (1871). So it'll be interesting to see if the details on the marriage certificate tallies with any of this.
