Dear Michael,
Thank you for your comments. I was trying to thank you but wikitree on my iphone is very frustrating. It kept asking me to log on and didn't keep me logged on . I tried 6 times and now on my computer it is ok. I tried adding Pat walker to my grandfather's profile. My full tree is on ancestry and I wish I could just transfer it. Not knowing my cousin, Pat Walker's married name makes it very difficult to trace her in the US. Anyway thanks again for you help.
