Rock of Ages

I came across this mourning figure at Heywood Cemetery in Lancashire. Unfortunately, the details of those commemorated has eroded and I have yet to discover any more information. Below the figure's foot runs the embossed words 'Rock of Ages' and, to the right of that is inscribed name of the sculptor - F W Bayon. Looking more closely at this memorial, it reminds me of a jigsaw and I wonder whether it had been shattered and put back together?
