Welcome to WikiTree Fiona. Thank you for introducing yourself to us in our g2g forum. As you already know, this is also the place where you would ask questions about your ancestors.
If you upgrade to a family membership, (which is 100% free), you would be able to add Wilson as a tag, and would be connected to all of the other people that are already searching members of your family.
Welcome again to WikiTree, and I hope you love it as much as I do.
