Dear all,
My entered message has been un-answered for so long!
This spelling of our name is now more or less extinct in the US (?). Lybrand is more common.
Even in Guendelbach - Baden-Wuerttemberg (Germany) this spelling is not to be traced in the present generation.
Meanwhile we DO have now a large Web-Page for the various spellings! (Made and maintained by: Hans Leibbrandt - Best in The Netherlands / Holland). Greetings.
