Here are Caroline and Samantha together. Caroline stands better than Samantha does, possibly because she does not have the overstuffed body of the Pleasant Company era. You have to balance the weight of Samantha's head against the weight of her torso, and balance both of those onto her legs, which weigh much less comparatively. Also, Caroline's limb joints seem stiffer. I don't know if that has to do with Samantha's age, or slightly different manufacturing. In any case, that also helps Caroline stand better.
here's a short few paragraphs talking about the difference between pantaloons and pantalettes. I'm not sure if these specifics applied as far back as the Regency, but I'm using them here.
Battle of Lake Erie. If you are from the US, you may recognize a famous quote from this battle, by then master commandant Oliver Perry: "We have met the enemy and they are ours." Caroline's story does revolve around her father's shipyard, but there was also a great deal of important ship building in Erie, PA. I'm biased myself, because I love Lake Erie and its history, but really, AG, we did not need another doll from New York state. :)
In Cleveland, the War of 1812 and Commodore Perry are still remembered, in various ways. :)
