pattymartin on Family Tree Circles

I'm looking for other martin family members or help to stay on the right track with my family tree. the martin sur-name is so big and everyone used the same names. my tree is the Martin/Hubenthal families and other then my dad Floyd martin (he used Floyd as his first name)I know none of them. My dad told me before he died he could have been knighted but he declined and that there was a castle in his family tree. here's what i have so far, i actually have gone further but kept stepping into other family tree's not related.
