Hart to Hart : Was Jonathan Hart married to anyone else before Jennifer?

I recalled there was an episode with the first Mrs. Hart meeting Jennifer
or am I crazy? Mind you I watched the show 35 years ago so my memory could be
play tricks on me.

I recently watched the series on Netflix and there wasn't anything like that. There was a Jennifer lookalike and a couple posing as the Harts, and a woman that claimed Jonathan was the father of her son, but he wasn't. Unless it's from the movies. I have not seen those yet.

Ryden, I also think this poster is thinking of "Jonathan Hart, Jr.," where she tries to pass off her son as Jonathan's. There was no first Mrs. Hart anywhere.

There are IIRC a few mentions of Jonathan's previous girlfriends including a rather odd display in With this Gun, I thee Wed. Jonathan seems really still taken with the old girlfriend.. It felt kind of weird.

I'm so freaking behind :-(.

Haha there is nothing in that episode that suggests that he was still taken with his old girlfriend.

There was an episode early on - I think it was "With this Gun, I Thee Wed" where they are invited to a wedding of the former girlfriend of Jonathan. I don't recall him being married before.

Yes, I was not an overall fan of that episode, but it had some great moments (including the bathtub). But yes, she was an old girlfriend, never married.
