March 1913 was a rather eventful month for Nebraska weather, which included the Easter Sunday tornado outbreak which killed several hundred people in the Omaha area.
As for early March, all I find mention of is a significant blizzard that hit the Norfolk, Nebraska region about March 1, 1913. It certainly could have hit the Madison and Newman Grove area too. The Grand Island newspapers indicate that this storm was predicted to hit Grand Island too, however, the storm ultimately missed Grand Island.
**It appears there had been a number of blizzards during this time, with one of the worst hitting around March 15-17, 1913, however I'm not finding any specific mention of snow totals or deaths.
