Julian, i am "always" researching the Orchard family!
I cannot place a William anywhere, save for maybe a middle name.
Having said that, i have just recently returned from Sri Lanka, met with an aunt who i only discovered last year, and she tells me my grandfather was one of TEN children! (we always thought he was an only child), SO, anything is possible. The difficulty is finding and accessing the records over there; it is not an easy process, but, the search goes on.
Thanks for the contact, if i do fit William in anywhere, i'll be sure and let you know,
Regards Keith Orchard.
