Well have not hear back about this. To update our record we just lost our male Van Santen. His father was born in Holland that came to America ca.1918 and his only known grandchild will carry our line forward. We hope he'll have children but only time will tell. There's a sample of our (Male) Van Santen's DNA left in the BYU study when Prof. Scott WOODWARD was doing it a few yrs ago. We did their blood draws and given a number; but I don't know if it's still any good. Last hear BYU was stepping out and Sorrgenson just came to mind as the Company handling it now. Would like to hear back about any of your current Van Sant DNA if your including any Van Santen varriants in your Group study DNA results. Thanking in advance. Cordially, P. WOODWARD
