This is a list of records for the surname Brocher (including variants Brochier and Brochet). I am researching the ancestors of Jean Henri Louis Brocher (abt.1809-1874).
Recently (2021?) , ancestry-com has picked up an index to the Belfort Department Archives: https://www.ancestry.com/search/collections/61787 .
I have excluded records that already appear on Henri's profile or his children.
Various records follow;
There is a death record for Belfort in 1827 of an Alexander Brocher, and his daughter Jeanne (I can't read the age - 2 something?) by Catherine Jokom (possibly unmarried). Maybe no relation. 
The 1881 census for Delle, on the same street and a few doors down from Julie is Jean Jacques Brocher, a proprietaire born abt. 1814.
