My mother-in-law had children her last three children at the age of 42, 44, and 47, and two of the daughters were old enough to have borne children, but this was not the case. She also had the last child at a specialty maternity hospital in NY that dealt with difficult pregnancies. And I myself was born when my mother was 42 and my oldest sister, who was 16, was shocked, embarrassed and indignent! A long time family joke. On the other hand, my g-grandmother had her last child at the age of 48 and had an unmarried daughter of 19 (who never married). In this case, though there were 10 children born very close together, there was then a gap of 8 1/2 years until this last child, which does make this birth very suspect. Before coming to a quick conclusion, check to see when the next to last child was born, and what the usual gap of years was between births. There's an old Irish conviction that it's best not to delve too deeply into your family history for fear of what you'll find. I heard that often researching my husband's family in Ireland.
