This is the only death I can see for Daniel

The year is the same as the Calendar of Wills 1906 not the expected 1908 but the age doesn't match the Census.
Death ages are often incorrect as it depends on who the informant is, but this is a good example of how every thing needs to be double checked, we have after all not found Margaret with this family we are still hoping she and Grace are the one and the same.
