It is good to know that they are brothers.Looking at dates given for Immigration on the census it appears that they immigrated in 1884. Do you know anything about this such as were they traveling together and were they the only ones.Have you seen any immigration records or Naturalization records.Do you know where in Switzerland they came from??
My stronger interest is in Elizabeth Willis who married Jack August Abt.My grandmother would be a youngest sister, Roxie Willis Klepper,to Elizabeth Willis Abt.Elizabeth Willis's mother, Mary Francis Ashley Willis was born in Smyth Co., VA.Her line have been very difficult in areas.Her line should be Elizabeth Willis b. 1891, VA[Wise County would make sense] Mary Francis Ashley b. 1866, Smyth Co., VA Elizabeth J Freeman b. 1827, VA [likely Smyth Co. or Wyth Co] Sarah Fleming. b. 1790 [ I have both, Ireland, NC, and VA:1860 census says VA]
I really like to look at families into the extended parts of the families. I find that far more interesting.
Do you need any information on Jack August Abt's wife's family.I would be more then happy to share what I have with you.
