Hi Pat. Helen Hamilton was definitely not the dau. of Lady Anne Hamilton. I'll dig out what information I have on her and send it. I've been cleaning out my files and you know how that goes. Now I can't find anything. If Margaret who md. Archibald Brownlee was dau. of the Duke, it would be a later Duke. Helen and Margaret were separated by nearly 100 years. You would have to find out who held the title at the time of Margaret's birth - early 1700s - and find out who his children were. I have no information on him, but it must be available somewhere.
