I've got them being married on 26 Mar 1878 in Shermantown, Allegan County, MI (source: Dibean Marriage Collection) and they both died in 1942 (her in Feb & him in Nov). So if the marriage year is right they celebrated their 65th wedding anniversary in 1943 which is impossible.... OR I've death dates wrong, which I doubt because I found their death records on Ancestry.com & correspondence with a granddaughter of theirs.
I celebrated my 40th birthday, and yes I did have a minor mid-life crisis... but I snapped out of it when my hubby gave me this gift & my zeal for research was renewed. I can't wait for some free time to make a trip to the State of Michigan's Library to get into some "old school" researching. :-) All in all, my birthday was a mildstone I will not forget anytime soon.
Much Love from Michigan
