I have a Warren Denison born in 1876 and died in 1963. He married Martha Lietha who was born in 1885 and died in 1975. I don't have much on the Denison family other than their children's names. I do have Martha Lietha's ancestors all the way back to the 1600s. The Lietha family was from Canton of Graubunden in Switzerland. Please let me know if you are interested. I will gladly share whatever I have.
