Jan's Aunt Jenny is the seventeenth episode of Season 3 of The Brady Bunch, and the 66th overall episode of the series. Written by Michael Morris and directed by Hal Cooper, it first aired 21 January 1972 on ABC.
Jan discovers an old photograph of her Aunt Jenny as a child that looks just like her, and worries she will resemble the old and eccentric-looking Jenny at that age, until she meets her and realizes her beauty within.
The Bradys clean the attic and Mike tries to restore an old record player he finds. Meanwhile, Jan and Cindy come across a photograph of Jan that neither remembers Jan ever taking. Their mother tells them it's because it's not a photograph of Jan, but of their Aunt Jenny, taken forty years ago when she was Jan's age. Jan wants a glimpse into her future and writes to Aunt Jenny asking for a current photograph. Jan regrets doing so as Aunt Jenny forty years older is an odd-looking woman, and Jan believes she will look like that when she's Aunt Jenny's age. Jan is even less excited when she hears that Aunt Jenny is coming by for a visit to meet the family, most specifically Jan. Jan can't hide her feelings about Aunt Jenny. She learns what the problem is, but is not offended. But over the course of her truncated stay, Jan learns that there are far more important facets to Aunt Jenny than what appears on the surface.
