The bloodlines trace a direct line of descent from the earliest known ancestor of a family name down to Mary Emma Sercombe. Each bloodline is set out in standard genealogical format. Surnames are capitalized to avoid confusion with given names. A paragraph outlining birth, marriage and death/burial dates for each person and his/her spouse is followed by facts obtained from verifiable written, photographic and (very occasionally) verbatim sources. Abbreviations are used where a word is recurrent, and there is a key to these [see site menu].
