This is quite a hoot, but a Leah Brooks was the spouse of Riley Mantor, of Mantorville, in Dodge county, Minnesota in 1854. He was certified to be a settler and early pioneeer. This listing was on a website just preceding the picture of Henry C. Hythecker, also a pioneer of Dodge county. http://www.dodgecohistorical.addr.com/
As a mater of fact, only a few of the first 30 images found had Leah Brooks in the top text. All of this shows you that in its attempt to deeg deep for a match, a search engine still doesn't get it. It takes the human intelect to sort it out. It's almost like the amazing Kreskin type "see-ers". It hands you some likely matches, and you grab the right answer and praise the engine, Like Kreskin says I'm thinking of a "G" who is sick, and the target says, How did you know my uncle George had cancer?"
