Thanks for writing back!
I don't know about the Baads in Michigan, except that they're there. I may indeed have a connection. My g-g-grandmother was a Baad. Her parents were Christian Friedrich Baad and Elisabeth (Magenan) Baad. I had assumed that Christian and Elisabeth came to America like so many others. After beginning my research, I found out that it was an entire family that came from Germany (Steinheim an der Murr in Baden Wuerttemburg).
The Baads settled in New Bedford, Coshocton County, Ohio. They were founding members of St. John's Lutheran church (now disbanded). My mom was from New Bedford, and much of my childhood was spent there. I am the last on my branch of the family tree to have been baptized at St. John's.
Studying the cemetery and the church book of St. John's, here's what I believed happened with the Baads:
Georg Adam Baad (1791-1867) and his wife Rosina Barbara (Ott) Baad (1796-1881) (and two brothers, Gottfried Baad (1796-1872) and Jacob Friedrich (1807-1888)) came to America with their children Christian Friedrich (1820-1881), Samuel Friedrich (1824-1891), Christian G. Baad (1830-1916), Louise Margaretha (O1834-1866), Christina (1836-1916), and Wilhelm Gottfried (1840-1879).
That last one, Wilhelm, I believe might begin the Michigan connection. Wilhelm moved to the town of Warsaw and appears to have operated a store. He married a Temperance Darling in 1865. The Darlings were a prominent family in the early days of Coshocton County. Wilhelm's store was located on a lot between the main street (now SR 36) and the old Canal. The canal is gone now, and the lot now holds the town fire dept. Behind his store, on the other side of the canal, was a large mill owned by the Darling Family.
Wilhelm and Temperance had the following children: Harriet (b. 1867), Joseph (b. 1871), and Frank (b. 1872). Wilhelm died in 1879 at age 38 and is buried in Darling Run Cemetery, just west of the town of Warsaw. Temperance remarried a Allen van Lien (Van Lehn?) in 1844.
The rest is off the top of my head. I think Frank Baad went to Michigan, and was later joined by his sister Harriet and mother Temperance. I found Harriet later at Akron Ohio living with her mother Temperance, now going by her old name of Baad. It sticks in my mind that I came across a death certificate for Harriet and Temperance and they were buried in Michigan. Does any of this ring a bell?
I kind of put the Baads on the shelf for a while because I'm working on getting through a brick wall on the other side of the family. The Baads have turned out to be very large and very spread out. I figured it would take a lot of time to get them all sorted out.
I'm descended from Wilhelm's older brother Christian Friedrich. His daughter was Mena Wilhelmina, and she was my g-g-Grandmother. Christian Friedrich had two sons, William Godfrey and Adam. Notice how the same names stay within the family?
Hope this helps.
