Karlsruhe, Baden, prussia

hi everyone,

I've been researching non stop about my 5x great grandparents who were from Karlsruhe, Baden, Prussia?
but i can't seem to find much information on them, so i would love some help!

John Tosler (born as Johannes Töißler) was born in Karlsruhe, Baden, Prussia on march 15Th 1783.
he married Susanna Mann (1776- no death date) in Hull, Yorkshire, England.
i am not sure when he and his family came to Hull, as i can't seem to find any records!
he died abt 1836.
his parents are
Johannes Töißler (no date of birth or death)
Elisabatha Kronerin (no date of birth or death).

I'm wondering if anybody could give me any tips or find any information on these people?
