Thank you for all the assistance. Someone explained what I was doing wrong-- trying to find parents already created by putting in their names and birth dates and expecting them to come up on a list of possibilities. I now realise that I have to hunt for them separately and put in their profile numbers.
I don't understand the question about specific data and source location. My source for this Lloyd line is:
Burke's Landed Gentry of Ireland, 1899. Pedigree for Lloyd of Lossett, p. 266.
Is this so problematic because it is before 1700? I would like to add two more generations based on a published source but I am hesitant to do this because of all the aggravation in doing this.
I think that I put this on every profile.
