Death Records Now

My great-grandfather, Ignazio Messina (b. approx. 1895), died in March 15th, 1925 in Michigan. I’ve searched and searched for his death records but ancestry.com has no record even close to his name. Does this happen often? Can anyone else find anything?
Wife: Nardina Dibella (b. approx. 1895)
Children:
Pauline Messina,
Bertha Messina,
and Anthony George Messina (b. 1931)

So…. how is it that Ignazio died in 1925 and….. Anthony George was born in 1931 !!!!!

Could this be them, listed as StepChildren, in the 1930 Michigan census?
