Thanks for your reply Jan. But I did do the Comparison and checked which of the names already there were the same profiles as my ancestors and I thought that I had done all that was required. I don't believe there were any matches except for ones that I had already posted myself.
I didn't receive any communication from Wikitree to indicate that my gedcom was not appropriate or that it would be deleted. I have sent people, Dna cousins etc, to look at it because I thought it was all there.
