My apology for posting this so late, but I just found this website tonight!
I have cousins named TRIPP and a friend whose maiden name was TRIPP.I suspect that this is the one that may be a connection to the TRIPPS you are looking for.I believe my friend has told me that most of her ancestors are buried in the Flora (Township Cemetery), so you might try looking there first.My cousins' father was named Harold--he and his first wife I believe are buried in the East Bonus Cemetery on the Woodstock Road.
Just had a thought. . . . . You might try also the Ida Public Library in Belvidere.Their Genealogy Room has been saving obituaries for some time (years).They can be very helpful.
