VERY impressive family tree. When you post, you should post the link so volunteers having access via Ancestry can see the Big picture of the person(s) you seek:
http://trees.ancestry.com/tree/28199691/familyFind-a-grave has Rudolph and Anna identified with the grave of Herbert Bertrum (Bert) Smith. I don't know if this is your written tribute or that of another. Most tributes were composed by those persons that take gravestone photographs; but, this one has family information. I have found tributes on this site that are NOT accurate. I have found persons listed that were actually buried elsewhere.
