Removing children elements given an index?

I've got a layout like this:

<div id='parent'>

    <div id='row_0'></div>

    <div id='row_1'></div>

    <div id='row_2'></div>

    ... 

    <div id='row_N'></div>
</div>

At some point, I want to remove all div "rows" above a certain index, like:

for (var index = 1; index < $('#parent').children.length; index++) {
    $('#parent').remove('#row_' + index);
}

is there a simpler way to do this in jquery? Something like 'just remove all children starting from index N'?

(the above for loop won't really work, but is the kind of thing I would do if there's no other way)
