I have just had a lovely time piecing together a family tree for an Ivison Family who lived in Carlisle in the 1800's. Everything was coming together very well until I found a grandchild (in 1901) with an unexpected surname, ie the same surname as the famiy's lodger in 1861... oh no does that mean he married the Mary Jane who I thought was my great grandmother... yes it did!
I now have a good looking Ivison Family tree which isn't mine! If anyone is researching Ivisons in Carlisle and would like a copy of what I have done so far please let me know.
I guess they could still turn out to be realted to mine, but I have yet to find the link.
