G-G Grandparents on my mom's side

These are my g-g grandparents:


Maternal - the Irish and the Germans


Jeremiah Quill married Hannah McCarty, both born in Ireland; married in 1856 Camden NJ
lived in Philadelphia, Ohio and St. Paul MN


James S. Rochford married Bridget Maloney, both born in Ireland; married before 1862, place unknown
lived in NY state and St. Paul MN


Heinrich/Henry Herbst married Louisa Lindroth, both born in Germany; married in Germany before 1845 
owned a farm in Leyden Twp, Cook Co. IL, an area referred to as Mannheim


Charles/Carl Dettman married Frederika Bahr, both born in Germany; married in Germany before 1860
owned a grocer shop in Chicago, IL on Lincoln St. (not Lincoln Avenue)


My Quill's have also been spelled and indexed in various databases as Ouill, Quesal, Quale, Duill and Gill.


The Rochford's are listed as Rockford, Rochefort, Rocheford.


Dettman sometimes has one 't' and two 'n's' or one 't' and one 'n'  or 2 't's' and 2 'n's'


Bahr is also listed as Barr.


Lindroth is more of an educated guess than a certainty, all sorts of spellings on that one.


I have found census records for all of the families above, from their first appearance in the US Census until their deaths. I also have all the death certificates, with the exception of the Herbst's. I have also been to the grave sites for all my maternal g-g grandparents, pretty amazing experience each and every time!


The most amazing thing is that I have found these family members at all. When I started all I knew where the first and last names of my great grandparents. As I began to research it was funny how all of a sudden some long buried tidbit would pop into my brain.  The death certificate for my grandpa Quill, Thomas J. (we called him Boo) had him born in Chicago. But then while searching for John Quill in FamilySearch.org I found one married in St. Paul MN to a Kate Rochford. Bells went off and I remembered my grandpa talking about St. Paul. Sure enough, my grandpa and 3 of his sisters were all born in St. Paul MN, not Chicago.


A census record for my great grandma Kate's brother listed one of his children named Clementine. Another bolt in the brain sent me looking through a box of photos and there it was, a picture of me with my grandpa's cousin Clemmy at my parents house in 1967.
