Well,, I was the only girl with two brothers and three male cousins in my immediate family so I know how that is !! I am still betting it was hers !! Sadly there is little value other than with your family !! Most of the traditional bed dolls were larger but I can remember these smaller ones from the 1950`s !! Many adults had them just as decoration and I was not allowed to play with them being the rough and tumble counterpart to all the boys !!
Hope I helped a little in your search !!
