I'm still working on my family tree... and finally made a break through on the one branch that had been impossible to find more info on... and my paternal grandmother's grandfather and great grandfather were bridge carpenters for the Michigan Central Railroad

The Michigan Central Railroad had several wooden bridges, including the Baker Street segment of the Double Bridge in Detroit, the Kettle Creek Bridge in St. Thomas, and the Saginaw River Bridge in Bay City.

the wood-timbered Baker Street segment of the 1870s-vintage Double Bridge was functionally-obsolete and replaced by a new concrete-and-steel version c. 1910. 

The Michigan Central had the most direct route across Michigan from Detroit to Chicago. The Michigan Central also had the best access to Chicago of any Michigan railroad.

and you probably recognize the station that Ford recently made a lot of headlines about buying... the famous Michigan Central station in Detroit

And also, I finally made the family tree connection my sister had been hoping for, I proved that we are related to Mary Queen of Scots. Way back during high school my sister did a book report, or essay or something on Mary Stewart, after watching the movie with Katherine Hepburn, Mary of Scotland, which also starred Frederic March https://www.imdb.com/title/tt0027948
