Back around 1880, Frederick & Albertina nee Ness Gartz arrived in the US. Settled in Rochester, NY for a couple of yrs., then moved on to Appleton, Wis. Had 16 children that came with them. Have found eight by name. Have letter copy which states the other eight left Appleton and headed west for California. Siblings were Alvina Maria, Olga Lena, Florentina, Emilie Caroline, Linia, Leo Leopold (my grandfather) and Heinrich Wilhelm later Anglicized to Henry William. Do any of these names sound familiar? Need help for all of their names have been lost to all living descendents in New York, New Mexico, Washington, Florida, Colorado, Connecticut, Illinois and here in Wisconsin.Thanks much for any help that can be given or any insights any could give to help me locate.
