Html – DIV moves when I put text in it

I spent some time creating a pedigree out of div layers on this site and I got it all nicely aligned.

But when I put text in it, whether just in the div or in p tags, it moves the div layer down significantly.

It doesn't seem to add any margin or padding or anything else I can see while inspecting the element, and it doesn't seem to be affecting the grandchild div layers.

JSFiddle

HTML:

<div id="pedigree">
    <div id="parentwrap">
        <div class="parent">test</div>
    </div>
    <div id="childwrap">
        <div class="child">
            <p>Am. Ch. Kenai's Aldebaran</p>
        </div>
        <div class="child">
            <p>pAm. Ch. Santa Clara Del Viento</p>
        </div>
    </div>
    <div id="grandchildwrap">
        <div class="grandchild">Am. Can. Ch. Ryzann's Eclipse at Kenai</div>
        <div class="grandchild">Am. Ch. Timber Ridge's Abi of Kenai</div>
        <div class="grandchild">Am. Ch. Sky Run Gavril Virtual Zip JC</div>
        <div class="grandchild">Am. Can. Ch. Tazeb's Zena</div>
    </div>
</div>
