Edward was born about 1862. He was the son of Samuel Grant and Matilda Ronger. Dna matches to the grant side of the tree. There are two Find A Grave sources which need collaboration to determine the correct gravestone for this Edward.
Research continues for Samuel Grant and Matilda Ronger’s grandchildren.
Thank you
I don’t believe this is his find a grave https://www.findagrave.com/memorial/38166323/edward-richard-grant
This Edward has different parents and children
Per familysearch sources I concur it’s a bit tricky both men similar names and dates of birth and death.
