It is fun to check what #Wikidata has to say of people and places prominently mentioned in #Wikipedia. The article about Mr Sherman is a featured article. There is always something to improve and it is now registered that Mr Sherman had a father, a grandfather and several brothers. Sadly it does not register in the Reasonator.
Mr Sherman was part of the "Opposition party", this is an article that needs some serious attention. The article describes three instances of an Opposition party and this does not make sense in the context of Wikidata. From the article it was not clear when Mr Sherman moved to this party from the Whig and later to the Republican party.
