PBS’ “Genealogy Roadshow” at 7 p.m. Tuesday will feature a New Orleans-set episode.

In the episode, a team of genealogists will uncover fascinating family stories at the historic Cabildo, now home of the Louisiana State Museum.

The hour will include: a couple whose ancestors hail from the same small Italian town who explore the chance they may be related; a woman desperate to find out who committed a gruesome murder in her ancestors’ past; a home held by one family for more than a century that renders a fascinating story; and a woman who discovers the difficult journey her ancestor took on the path to freedom from slavery.

The show will air on WLPB, Channel 27 (cable Channel 12).
