Okay, I started with a quick look at census, found them in both 1880 and 1900 without problem. I see Henry, Barbara, Antonia, and Emma living in White Rock Village in Huron County in 1880, ages 43, 40, 16 and 5. So Antonia is right on, but as is typical in census, ages can be off for adults. By this, Emma would not have been 5 when she immigrated if they came in 1878. The name is spelled Wollman in this census. In 1900, it is spelled Woolman, the parents live in Sherman in Huron County. In 1900 get Henry b. Oct. 1833, Barbara b. Oct. 1837, probably more accurate. Immigration 1878, and he has papers applied for. So-- there probably is Declaration of Intent to find for him. That could be useful, especially after 1900. She is mother of 6, 5 living. Okay! We have some more children to find. They are probably older than Antonia, so at the 1880 census, they were married off, or working on another farm, or something like that; or adult children may not have immigrated.! She was probably oldest child still at home. Well, I would definitely get EVERYBODY's obituaries in a local newspaper, and see the mention of other children or siblings. And looks for boys named similar spelling in county or nearby. And look through church records for Catholic churches in that county and nearby for marriages of other children. Note that in 1880 census, origin is listed as Germany and in 1900 Austria. This is very common with German-Bohemians, you see this all over (my families show Germany, Bohemia, and Austria for the very same family, too, and I do know where they're from). Bohemia was part of the Austro-Hungarian Empire at the time of immigration, so Austria shows up a lot. Linda
