As both Colin and Barryd have said, it is easier to pick one spelling, and stick to it. Record any variations you may find in attached notes for future reference. This way, you keep track of the various spellings you encounter, but keep finding individuals in your family tree program simple.
I am Australian, from all the lands I come (my ancestors, at least!)
Pine/Pyne, Dowdeswell, Kempster, Sando/Sandoe/Sandow, Nancarrow, Hounslow, Youatt, Richardson, Jarmyn, Oxlade, Coad, Kelsey, Crampton, Lindner, Pittaway, and too many others to name.
Devon, Dorset, Gloucs, Cornwall, Warwickshire, Bucks, Oxfordshire, Wilts, Germany, Sweden, and of course London, to name a few.
