Hallo, Thanks for all your answers but if the register doesnt show place of birth for Catharine or her fathers name, then looking at it wont help much, although a family witness of hers could be a long shot. I am searching for the birth of Alexander Pikeman c1770. The only record remotely near that date is in the Isle of Man. Alexander married Clarinda Scroggs and he had a sister Catharine.
Now we see a Catharine marrying a Scroggs, very tempting to draw a conclusion but it could be one of life's coincidences. Thanks again, Mestalla
