Not a shot in the dark. I noticed a couple of people were researching that side of my family and was hoping one of them would see my message and maybe have some pictures they could email me.
most TP members do not visit the forum ... so you would probably be better off searching for the sites where you found the researchers on the family and contacting them directly. Friendly, helpful and very flattering usually works well.
If you saw requests about that research on the forum - try to find those messages again. They may never have come back but you will have contact info.
