Tunis & Weers Family of Illinois

I am searching the James Tunis & Christina Dalton Family.I have looked many places but have yet to come up with these two as a family. I have come to the conclusion that it could have been Jacob Tunis & Christina. I have found out a little bit of them and they had a son named James of the right age. Anyone with any information about Christina I would appreciate as I have hit a brick wall.

Also I am researching my grandfather Michael Roland from Dublin, Ireland's family. I would appreciate any information anyone could give me.

Henry Weers from Lacon,Il (Ofstriesland, Germany) was my husbands grandfather. I have found a lot of his family but if anyone has anything they could share with me, I would appreciate it.

Also George (Green) DeFord of Ohio was my gr-gr-grandfather.
He married Emily Knott.
