I have seen the name spelled many ways Wicht Wiche Wychet Wycht Wyche. I have found that there was an Abigail Wyche that married a Brewer, but I have not been able to make any connections.
Wicht's daughter Luvenia was my great-great-great-great grandmother. She was married to Albert G. Pettey(Petty). Their daughter Corin(spelling varies alot on her name also) Florence Petty married Benjamin Bledsoe.
