I lost part (or all who knows) of my husband's grandfather in the fireplace now I can not sleep?

Earlier today my husband was gone I was cold and building a fire. I had the poker over my shoulder but then the telephone rang I turned around and the poker knocked the urn of my husband's grandfather's ashes off the mantel and it spilled into the fireplace ash. I tried to get as much of his grandfather as I could back to the urn but I have no idea how much is grandfather and how much is fireplace logs. I did not tell my husband and now I feel so bad I can not sleep (it is past 3:30 am here).
