I am looking for Lillis Genealogists in Oregon. My GG Grandmother Johanna Welsh married Maurice O'Brien in Olive Township Clinton County Iowa in 1870 and her sister Ellen married a Maurice Lillis, after which the Lillis' emigrated to Oregon. We believe Maurice Lillis was Mormon.
We have run into a brick wall with Maurice O'Brien back. We know he was born in English Canada but we don't know where and are hoping that one of the "in-law" lines may have some info.
