Adrian,

Excellent point. I don't know why I put active in the contacts table as it
does make more sense to put it in the people table (as some clients have
multiple sites, each with its own contact person).

I don't recall which query I used for the MWE. I'll move the active column
to the new table, as well as those values, and keep working on learning how
to formulate complex, multi-table queries.

Also, moving the active table to peoples, where there is only one row per
person (rather than multiple contact rows per person) removes the need to
find only the most recent row in the many of the one-to-many relationship.

Thanks for the advice,
