Orchard Family: Yate and Old Sodbury

I am trying to make contact with living males with surname ORCHARD whose ancestors were from Yate and Old Sodbury. I am almost certain my Great-Grandfather James Orchard is the James Orchard baptised 27 March 1803, Old Sodsbury son of James Orchard 1763 Yate/1851 Old Sodbury and Hannah Carter. 
I want to sponsor a Y-DNA of a living male Orchard from that family to confirm if my South African Orchards ancestors were not related. All male descendants with the same family surname have the same DNA markers accross many generations. My James Orchard married in Cape Town in 1832 and indicated his previous residence was Bristol. Kind regards. Evan Franklin
