Recognize these plastic dolls?

These dolls belonged to my aunt, but I have no idea about the history behind them. Each doll is about 10 inches tall. They look similar to the collectible dolls from the 60s described as Arco Gas Station dolls, or Blue Bonnet Margarine dolls. But, none of these dolls seem to match any photos I've seen of those collections. Does anyone recognize these, or have other ideas?

Thanks in advance for any information.
