Just located the Joseph Srackengast family in the 1850 Census. He was living in White River IN (Hamilton Co) with 2nd wife Elizabeth and all his kids from eldest John W down to an 8 month old named Mary born in 1850. The cemetery files did't list a Mary born in 1850, but give a Christina born in 1853. So maybe this Mary died in infancy and is buried elsewhere? The cemetery files are from Madison CO, where Joseph is buried, but the census is Hamilton Co. I'll have to search now for the 1860 census to see what's there, although that census is a "pain" to figure out. It's still in bits and pieces at the LDS site....individuals that can only be tied together by a family number.
And I also found in the 1880 Census John W and his wife Mary K Srackengast in Hamilton Co with a son John W born 1858. This John W is Joseph's son born in 1825 in VA.
Got a map of IN to see just where Madison and Hamilton Counties are in relation to each other and in relation to Berrien County MI, which is in the far SW corner of MI. Both Hamilton and Madison Counties are just north of Indianapolis, so about 150 miles from Berrien County.
Also located some Pennsylvania Shreckengasts in Randolph County IN which is to the east of Hamilton and Madison Counties but I don't know if they are related??
As to George Srackengast which you say is your husband's family, I can give you the URL to a map of Pipestone Township in Berrien County MI from a book in the U of M Library entitled "Atlas of Berrien County Michigan", in 1887 that shows the land (two plots) owned by Mrs Geo Srackengast that is near to an 80 acre plot owned by my GGGrandfather William Griffin. It says Mrs Geo Srackengast on it because George died in 1886 and this book is from the year after he died.
I also once located some Srackengasts in other parts of MI... like Cass County, which is just to the north of Berrien County and Lenewee Co which is farther east. Got to run these folks down... when I can...to see if they might be related. These folks were another generation, I think... from the 1880s and 90s?? Maybe George's kids that spread out a bit??
