I'm so relieved that this group will continue. So far I've not found any "cousins" but hope springs eternal.
Walker, Harper, Richardson, Beilby, Clark late 1700's all in the Seaton Ross, Holm Upon Spaulding Moor, Beilby, Market Weighton areas of East Riding
Bailey & Emery in 1600's Almondsbury & Huddlesford West Riding. I'm not spending time on this right now because it's too long ago and I have more important fish to fry. Of course if I can get more information I will do a happy dance.
Possibly Ward in Yorkshire. Probably Bef. 1700 It's still a stumbling block at this time.
