Hi there,
If the bride, Jane Rayner had been 21 when marrying, then she would not have required consent to marry, and thus the mc would not have included her father's name in central section.
But he was William Rayner, a Farmer and most likely he was at McDonald's Creek

because ....
NSW ER 1870 MUDGEE
William RAYNOR (with an "O") residence McDonald's Creek
William RAYNOR, junior, residence McDonald's Creek
There were also chaps surnamed RAYNOR nearby :
Robert with freehold at Pinebone, William with freehold at Pinebone
James, residence at Barragon
Henry, residence at Guntawang
and at Triangle Swamp there's 3 .... James, senior, with freehold; James junior residence; and John with freehold.
and at Sawpit Gully there's William and Thomas, both with freehold
and at Mullamuddy there's Samuel and Robert, both with freehold
Cheers, JM (off to look for likely surname for the witnesses !)
