Thanks larkspur, I do have that one on a list of potential parents for Cornelius. But in the absence of a baptism for Cornelius we can't really say much more. I think I need to explore other routes - wills perhaps - to see if Robert Bowman and others left any trace. A bit hard to do from this side of the planet, but I'll add it to the ever growing list of things to check whenever I get back to visit the UK.
