How to read this page

Photos and clippings count items you can view here.
Cited or transcribed records are counted separately.
Story links lead to accounts about the person; “Mentioned in another story” marks a passing reference.
Memorial links open Find a Grave.
A “family recollection” label marks something a relative remembered, not a written record.
A military-service label rates the record of that service, not the whole life.

Sex is as recorded in the family tree. Age at death is worked out from the dates shown and may be a range or an approximation. It is left out when a date is missing or is only a “before”, “after” or “between” date, when the research has found a date Unconfirmed, when the two dates conflict, or when they would mean an age over 110.
