This is my paternal-paternal line. It is pretty complete up until my great-grandparents: Henry and Elizabeth. However, I have never discovered the surname of Henry's mother, George's wife. I only discovered George's antecedents about ten years ago when I had an email from someone who noticed the similarities between our families in Ontario in the mid 19th century. After a bit she came up with a letter written by her direct ancestor back to his father in England. The letter, written 1847, must have missed the post. It had the complete address in Yorkshire on it. In the last sentence, her ancestor, another Henry, mentioned his brother George. I live in England, not far outside London. The next morning I was on the train to visit the Family History Centre and the Society of Genealogists. Before the end of the day I had matched George's baptismal date to the date on his gravestone in Ontario.
