Judy is my cousin, (maiden name is Jakubowski) I will get you copies of everything I can find for your Joseph. There very well maybe two, as it is a popular name, with it being biblical. I will forward your contact information to Judy as she has a great deal of information as well.
I will get a copy of the bible page from my dad or judy for some reason i can not find it here in my office. I am still putting all of this into a fomat which can be used without haveing stacks of things.
I would love to get copies of the records you have mentioned.
One more thing we have Martinus year of birth as 1858, this is a year after your Joseph.
I have a polish site that I get information from I will find the link this may be helpful.
