Hi,

I am descended from Marie Antoinette Karoline Friedrieka Bosse (I have also seen the last name spelled Boße) who was born in Königslutter, Braunschweig, Germany in 1849. She married my great-great-grandfather Friedrich Wilhelm Theodor Wilke 1 Jan 1869 in Königslutter. I do not know if she might be related to the Bosses you are looking for or not.
