I personally have very little info. on the Jabaays other than they are related. However, I have a cousin who has done quite extensive research on the Jabaay/Wiers connections.
If and when I can get her e-mail address I will forward it to you.
Pls. do not expect anything soon, as we are leaving 1/28/04 on vacation and will be out of town for about 6 weeks.
