Please do not upload any unsourced gedcoms. Just dealing with one lot now. You are actually far better to go slowly and carefully through the info you have checking it against any already on wiikitree and making sure you have reliable, preferably primary sources for profiles that you might need to create if not already on WT. Ancestry trees are not a reliable source, but if they have a primary source cited check that is correct and then you can use that source.
I hope that is a little helpful. If you are looking at English ancestry then joining the England Project and doing their Orphan Trail would helo you.
