In order to post profiles for the Strock name, you need to first create a free account on WikiTree.Just go to www.WikiTree.com and in the upper right hand corner, click on "Login".Then select "Create an Account".
Once you've created an account, you have a few options.You can either export a GEDCOM of your whole tree to put on WikiTree, or you can export a GEDCOM of just your Strock ancestors to put on WikiTree.
If you don't want to export a GEDCOM, then you could always manually create your tree, person by person.
Hope that helps and thanks for asking!
