I have a Louisa BRAASCH (b. 1845; d. 17 Sep 1925 in Olean, NY, USA). She was married to Carl Pott (my g-g-uncle) in Lancaster, NY. They travelled together from the Port of Hamburg to NY, arriving 15 Oct 1866.
The Hamburg ship register listed Carl as living in Scharstorf, Mecklenburg-Schwerin. No listing was entered for Louisa but she must have been from close to where Carl was from since they travelled together.
A piece from the local newspaper, 4/19/1902, says she went to Chicago to visit her mother but gives no other details.
Does any of this help you?
