MT, that sounds fantastic! I'm even more jealous of you!
Interesting ideas, Gothick! I suspect that they would also have had a butler and a footman or two. [spoiler]In the last episode of all, in parallel 1840, we meet "Harris, the second footman"![/spoiler]
Ben tells Angelique that he knows all the horses' names, so I imagine he took care of them as well as chopping firewood and carrying buckets of water from the springhouse to the kitchen and any other kind of heavy work that needed to be done. [spoiler]Soon we will learn that he can make simple dolls and knows at least basic carpentry. [/spoiler]
We know that Jeremiah and Josette had their own horses. Barnabas and Joshua would have as well. It wouldn't surprise me to learn that the countess was an expert horsewoman, but I can't imagine either Naomi or Abigail riding. Maybe Naomi did as a girl, but once she was married Joshua probably insisted that the Mistress of Collinwood should travel only by carriage.
Too bad we never see Cook, I agree. I'll bet the bad food at Collinwood was also a long-time tradition.
