Male or Female is the sex recorded in the family tree file, not a description of gender; it is left out where the tree does not record it. Age at death is worked out from the dates shown: exact when both dates are exact, otherwise a range (73 or 74) or “about”. It is left out when a date is missing, open-ended or conflicting, or when the dates would make someone older than 110, and when the research has labelled one of the dates Unconfirmed. People who may be living have no summary.
