Ernie Martin is an unknown quantity at this point
Two points.

First, a suggestion that may come a bit late is that a 1/4 inch nick on the leading edge of a prop blade does not necessarily mean it's unserviceable and needs replacing. The mfg establishes certain acceptable width at specified stations and if your prop has that width, it can be overhauled with the used blade (or if recently overhauled, the blade can be dressed and the whole assembly inspected and balanced by the prop shop). I know this from experience because my rear prop had a similar nick (1/4 inch or larger); I had it measured before it was overhauled this year and I knew that it would pass.

Second, I don't quite understand the sequence that lead to the two damages. Are we saying that an object (perhaps a pebble) bounced forward after nicking the rear prop and hit the aeleron?
