Well, I'm not real sure on my info other than my GreatGrandfather Joseph was born in Hrotovice in either 1839 or 1843.In the 1880 census it said he was 37.He was married to Anna #1 and they had four children as far as I can tell; Josey born ~1868, Joseph born ~1870, Frank born ~1872, and James (Vincence) born 1877.All but James were born in Moravia/Bohemia.I have that James was born Feb 2, 1877 in Nebraska.Anna #1 appears to have died giving birth to James.
Sometime or another GG Joseph married Anna #2 (Kucera) who had a son named Joseph by a previous marriage maybe in 1871.In the 1880 census she was listed as being 33.Looking through some old e-mails there is a message from a Teresa Lang who had info that Joseph married Anna (age 30) on 9/10/1877 in Wahoo, Saunders Co., NE
My GG Joseph's parent's names were Joseph & Katherina .Joseph Sr appears to have been born ~1805.Katherina was born ~1809. She is listed as being 76 in the 1885 census but she is not mentioned in the 1880 census (must have been away visiting).
GG Joseph filed a Homestead claim in Saunders County 11/30/1878.In 1880 he's in Saunders Co, Elk Precinct, maybe in the village of Newton.
It looks like GG Joseph & Katherina & family immigrated before 1877 or 1875.
