Elaine, I can well understand that you want a perfect fit. However, I have learned from experience that often our ancestors were sometimes deliberately vague at times. When a man wanted to join the army, for example, he often rounded his age up to ensure his enlistment. Think how many lads lied about their age to join up in the 1st World War. The recruiting personnel often conspired not to question their stated age. Possibly the same happened in this case? Anyway, I shall keep your dilema in mind. best wishes, Gordon.
