The direct line may not be the only approach when hunting an elusive ancestor. All aspects of obituaries should not necessarily be believed. The person who knew all the facts is dead. Other records such as censuses also have errors, as do transcriptions. As for the KNIGHT connection, I was able to trace William Knight’s parents, William KNIGHT and Caroline née WOOLCOCK, and his grandparents. His grandmother, Grace STANAWAY, was easily traced back to 1730s, but the KNIGHT family had too many James, William and John Knights to sort it out beyond the grandparents.
