I would love it if you would email me a copy of Elza's Death Certificate. Are you familiar with many of Elza and Levica's children and grandchildren's pictures? I have a dozen or so pictures of the Halfhill Reunion that took place at Krug Park in St. Joseph, Mo in 1951, but I only have names for very few of them. Could I email them to you to see if you can identify any of them. I'm going to email them to April Olheiser, as well, if that is okay with her. Can you both recieve hefty emails? I have a lot of pictures of Halfhill's from NW Missouri.
I know that Elza & Elmer were twins, but I don't know anything about Eleanor. My mom said there were triplets somewhere in the Halfhill family, but she doesn't know who they were. I've only seen reference to Eleanor in the 1860 Cheshire census, and I took that as an error as, Elmer wasn't listed. Their mother's obituary (Elizabeth Barrett Halfhill) didn't list an Eleanor, either as a living or a deceased descendant.
The reunion in 2010 sounds like a nice idea. I hope that pans out.
By the way, I live in NW Missouri.
