How this answer is built

Lines on the record come first: sourced links that no one presents as their own account, each with its strongest source. Then every account recorded here gets its own column, A to Z, none ranked above another. A column quotes only that account's own words and shows the strength of its own sources. Disputed lines are listed apart, with the reason, and lines still being verified come last. Neither is counted. Withdrawn lines are never shown.

What was recorded about an earlier form of Marathon Oil, the same body under an older name, answers too, and each such line says so.

When a list is longer than the page shows, the links the public methodology ranks strongest stay (methodology 0.3), and the rest open in the explorer.
