I'm not sure about the side-by-side farms, but Anna Ficenec was my great-grandfather's older sister. Here's what I know about her and her family:
Anna was the second oldest child of Jan (John) & Barbara Ficenec. While her parents and older brother emigrated from Koutnice,Hradec Královy,Bohemia in 1863, they didn't settle in at Suanders until 1871.
I don't have Anna's birthdate, but her older brother John was born in 1859 in Bohemia, and her younger brother Joseph was born in 1866 in Iowa, so she's somewhere in between. She was the oldest daughter, and we've been told she married someone neamed Agger, and that she died around 1913, + or - 3 years in Nebraska.
In the 1880 Census, she's not listed in the Ficenec household, (and neither are her 2 sisters, although her 4 brothers, father, step-mother and 3 step-sisters are listed), so presumably she's off married at that point.
Hope this has been helpful. Pleace feel free to check her out at our family website www.ficenec.com
, or e-mail me if you have additional information on her family.
