I have info on some WI Lorangs. Catherine Lorang, daughter of Dominic Lorang/Catherine Didier married Michael Spartz. The Spartz family came to WI through Milwaukee (Granville) and Washington County. Michael and Catherine moved to Ozaukee County in 1867. Catherine died in Holy Cross, WI in 1893.
Peter Larang is in the 1855 WI census. I think Larang should be Lorang as he is listed next to Michael Spartz. He immigrated from Holland in 1855 and lists 1818 as his birth date. I have possible brides to Peter as Maria Ulweling (deceased) and Elisabeth Reiter (marr. 1/31/1865) Peter was 48 at the time of his second marriage. I can't find Peter in the 1860 or 1870 census. Peter and Elisabeth are in the 1880 census index in Kewaunee County, WI. with 2 children, Susan(14) and Peter(10). Susan was born in Nenno, WI. Ss. Peter & Paul Church. I can't find Peter (Jr)
Interested in sharing any info about the Lorangs in WI. Thanks.
