Fancy finding you here! From what I was told by my grandfather, Ernest and Katherine had Christian, Ernest, Marie, Katrina(who went to Berlin) and ? Karl.Marie had a baby named Albert, who died. I went to Diekirck, Luxem a few years back and found a bunch of graves belonging to ersfelds.One of which was Katherine, not sure if she was "the" one. Hope all is well with you!
