Please reference the oldest federal code defining legal marriage for federal employment purposes.

The date was 1780, the Continental Congress ""The first national pension legislation for widows was a Continental Congress resolution of August 24, 1780"".

The 1780 Act was enlarged in 1794, 1798, 1802, and so on.

[Amendment10]

The date was 1780, the Continental Congress ""The first national pension legislation for widows was a Continental Congress resolution of August 24, 1780"".

Thanks for the reference. That's good information.

However, the resolution doesn't officially attempt to define marriage imo.
