Hello, looking for advise on how to search for the name of an unknown ZIPFEL, likely from Saxony, Germany, either 1868 or 1870, possible intent to go to Milwaukee, or New York, Erie County. Child Frank, came with them, b. 1866, mom survived the trip but died 1 yr later in Milwaukee, WI. Don't yet have death certificate of Frank, but do have obit, probate and know names of aunt, uncle, but no parents are listed. Thanks for any leads!
