This too is something I have been trying to learn as my surname is Skym. I have been able to trace my ancestors back to London England and have a few dates and names but not much info than that. I would love to get in contact with this friend of yours from England and exchange family info, would be interesting to find out if we are somehow related. Not sure how we could go about doing this but please contact me if you are still doing your research. I have already started a family tree on here so you could share that as well with your friend.
