JDR at Anglo-Celtic Connections set out to find the top ten genealogy words in the 31,127,950 mailing-list messages archived at Rootsweb.
Appearing in 2,736,649 documents, death was slightly more popular than marriage, which may say more about marriage than death. Both were mentioned more than birth.
Despite there being more women than men genealogists, males were mentioned more often than females. Daughters were mentioned more than mothers; every mother is a daughter but not every daughter a mother.
