JSON'd localStorage array of GMap markers get parsed as non-markers

Question

I've already asked numerous questions concerning the project I'm working on now and have hit yet another wall. I'm storing an array of Google Map markers in localStorage as a means to store searched history from the user. When I pull the data back out of localStorage via parse and retrocycle it, it appears they are no longer "Marker" objects anymore. Despite this, I still see most of the values that I should (i.e. a latitude and a longitude (only they aren't really named that)).

Here is my code:

var markers = [];
var cache = localStorage.getItem("searchHistory");
testCache = JSON.retrocycle(JSON.parse(cache));
for(i = 0; i < testCache.length; i++)
{
    newMarker = new google.maps.Marker({
        map: map,
        title: //what to do here?
        position: //what to do here?
    });
    markers.push(newMarker);
}
//On places_changed create new marker for location
addListenerToMarker(map,marker);
if(!markerExistsInMarkers(marker,markers))
{
    markers.push(marker);
    localStorage.setItem("searchHistory",JSON.stringify(JSON.decycle(markers)));
}

I've tried several things like:

position: new google.maps.LatLng(testCache[i][1],testCache[i][2])

Which supposedly worked for someone but it's showing up as NaN for me.

And:

position: testCache[i].position

Doesn't work because it's not a marker object anymore. How can I access the fields in testCache in such a way that they return what I want them to?
