Rospierski line

This is all I have on the start of my maternal grandfather's father's line...

Jan Rospierski married Marianna Wojcik  (Wójcik) 

These are their children. You might notice that the surname spelling differs with the siblings. This is not a typo but a choice that the children made. 

1. Adam Rospierski b.1886 d.1973
2. Jozef Rospierski b.1892 d.1944
3. Urszula Rozpierska b.1893 d.1968
4. Agnieszka Rospierska b.1896 d.?
5. Marianna Rospierska (dates unknown)

Agnieszka Rospierska

So far all I know is that Agnieszka Rospierska was born in 1896. I am unsure of her date of death. She married Michal Mikus and they had the following children together:

1. Helena Mikus
2. Zofia Mikus
3. Stanislaw Mikus
4. Jadwiga Mikus
5. Marian Mikus

I do have some information on their descendants, but I'll post that later.
