I have a Peter Verba that was living in Detroit, MI in Feb. 1958 when his father John Verba, SR. passed away. The obit also lists all of Peter Verba's brothers & sisters including one John L. Verba. Peter had a sister, Frances Sladek living in Wyandotte, MI during 1958.
John L. Verba who married Marie Stetz, died Jan. 13, 1973 in Cleveland, OH.
Let me know if this matches the information you have, as I am researching this collateral line as well.Deb
