Sorry that I am two years late in replying, I have been busy!Now, I saw that too. In 1870 it says keeping house, but I am not sure if she was his wife or a housekeeper. I got my information directly from my mom! She has the family bible. I figure the Mary E. and Maria to be like the universal first name that was not used! I will ask my mom again but we need some other proof since the census was written down according to the person who answered the knock on the door! And it has to be interpreted as having many errors. Nicknames were used and people were rarely totally honest about their ages. People lived in extended families and often, had the same names or names too similar and had to use a nickname.
