I am not certain if we are related or not.My Granfather's name was Fredrick William Dornberger, he had to sons, Fredrick William( Bill) and my Father, Richard Edward.I did find one reference to indicat that my uncle Bill one used the Moniker, Fredick WIlliam Dornberger III indicatint that my great grandfather was also Fredrick William.
My Grandfather married Alice McPheely, I do not know the date.
He lived the last 20 years of his live in Lancaster, Ca.
That is all that I have been able to discover.
Any thoughts you might have in helping me proceed, would be appreciated.
