Hi Judy. I recently got a box from my husband's Eaton side of the family. It was found when his 94 year old mother moved out of her house. The box is wooden, has Geneva Optical Co., St. Louis, Mo. written on the top. The box has a post mark as if it were mailed from Mo and a date of 1904. I researched the Geneva Optical Co which led me to your Elisha King Eaton. He was a partner with William Spencer and they made microscope lenses and sold them under the name Geneva Optical. I am wondering if this is coincidence or if there is a connection between your Eaton's and mine. My Eaton was Leonard who was born in Kentucky. The later Eaton's came to Texas. Does any of this ring a bell. I can give you other names and dates. Hope we can come up with something because I am stuck. Thanks.
