A coat of arms (COA) is owned by an individual, not by a family or clan. Any one particular COA is not meant to be passed down to descendents as is. Each family member was expected to add to it or take away from it as desired in order to personalize it. Or a family member could create their own from scratch.
But I post it here as a bit of Nicodemus family history.
As to the emblems, here are their general meanings:
The oak tree is a symbol of strength.
The symbol on the oak tree is a runic symbol for man.
The gold bar with the three "legs" is called a label and is a symbol for the firstborn. This is used only while both parents are still living.
The laurel wreath is a symbol of victory.
The lily (set on the blue escutcheon, or shield, in the center) is a symbol for purity.
BTW: I create coats of arms as a hobby. If anyone is interested in having me help them make one, I'd be happy to. I don't charge any money for this.
