I'm searching for information on my G.G.G.Grandfather Henry Spiegelberg. His daughter Lucy married my G.G.Grandfather Frederick Roper. Henry was born in Ohio around 1845 and was married to Catherine Amanda Garber. The family's entry on the 1870 Michigan Census is as follows:

Dexter Township, Washtenaw County, Michigan, July 16, 1870

Name, Age, Sex, Occupation, Place of Birth
----------------------------------------------------------------
Henry Speigelburg, 25, M, Farmer, Ohio
Catherine, 24, F, Keeping House, Ohio
William, 5, M, ---, Michigan
Edward, 3, M, ---, Ohio
Lucy, 2, F, ---, Michigan

Also on the same page is:

George Speigelburg, 26, M, Farm Laborer, Ohio
Adam Speigelburg, 30, M, Farm Laborer, Ohio

Possibly all brothers?
