I found this post on Ancestry.com:
Subject: ANTHONY & MARGRETHE ENGLER/WILLIAM FISCHER-MADISON WISC:
Hi looking for information/relatives on a great, great uncle WILLIAM FISCHER. Born to Martha and Johan FISCHER in Langland Denmark, approx. 1858. Immigrated to America with his brother Edward in 1881 to Iowa, moving after first year to Grayling Michigan. Died in Compton California after 1915 (?). He married Marie Johnson and had eight children two who died in infancy. THe six remaining; Mrs. Margaret ENGLER (MR. Anthony R. Engler married January 1, 1908) and William FISCHER of Madison Wisconsin, Mrs. Camilla Sorenson of Grayling MI, Mrs. Lillie McPeak and Mrs. Vita Shanahan of Grayling MI, and Mrs. Anna Hodge of California.
His other siblings: Edward, Rasmine (minnie) Otsen of Colorado, Hedwig (Rasmusson) Hanson, Emilie Sorenson, Marie Peterson, Anna Olson all of Michigan
So, it stands to reason that my great-great-grandfather William Fischer, from Langland Denmark, had a father named Johan Fischer. So the name comes from my great-great-great-grandfather from Denmark. Looks like they lived in Grayling, Michigan (from that post) which helps me figure out how the “the Engler side of your family hails from Michigan” part of the Engler history I’ve heard…
That Anthony R. Engler that married William Fischer’s daughter, Margaret Engler, was the same Anthony Engler that was my great-grandfather that was mentioned in Time in 1943, I think.
