I'm looking for the deaths and burials of Eugene "Gene" and Minerva St. John. They were on both the 1920 and 1930 censuses in Porter Twp.

Eugene St. John was born about 1881.
Minerva [Durfee] St. John was b 17 Dec 1886

He was a farmer. They had 8 children. If anyone has access to marriage records, I'd like to know the marriages for any children who married in Midland county. Their children:

Edward b 1906 d 8 Oct 1988 Gratiot Co.
Charles b 1909 d 1984 d 26 Jul 1984 Gratiot Co.
Frank b 1911 m Ethel M. Gallihugh 31 Aug 1939 d 21 Dec 1994 Gratiot Co.
Mary/ or May b 1917
Howard b 1920
Lloyd b 1922 d 18 Feb 1998 Hope, Midland Co.
Pearl b 1924
Clarence b 1926 d 1 Sep 1983 bur Porter Twp., Midland Co.

I've found death dates for all but Howard and the 2 women.

I'd appreciate whatever info anyone might be able to supply.
