The same records revealed, however, no such benefit from fathers and grandfathers. Whereas having a father around did seem to aid children in getting married earlier, a living papa did not increase the number of grandchildren.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciam.com/article.cfm?chanID=sa006&articleID=FAEB4508-E7F2-99DF-329AA2F69CCB6D5C&pageNumber=2&catID=2"><P>
