I,too,am researching Callahans (w/their many different spellings) from the Wauconda area. I am looking for a Mary Callahan who married a Patrick Finnegan. They had 3 daughters in the 1860s and lived in or near Wauconda. At least 2 of their daughters are buried in the Transfiguration Catholic Cemetery. Any knowledge of these people?!?
I have found a lot of information about Wauconda Callahans
on ancestry.com and suggest you try looking there.
Hope to hear from you via email: firstname.lastname@example.org
