I have been researching the family name since 1983. I am from Bristol. My family has lived there since circa 1794. Before this they lived at Christian Malford in Wiltshire. There are however, records of Pinkers living in and around Bristol in the 1700th century. I think there must be a link! I have manage to link my family with Families from Box, Wilts (now living in Australia.) London now living in Bexhill on sea. I have not yet link myself to another Pinker family living in Bristol Today. Again there is some thin evidence to link them to me. It's my guess that you are linked to the family of Pinkers that derives from London (18th century) I could be wrong though!
I would be very interested in hearing from you and any information you may have on your family history. I am sorry it took so long for me to come back to you, but, I posted my original message when I was very green re: the internet and had forgotten about this website.
I hopt to hear from you soon,
