This Sunday, May 11, as families shower mothers with cards, gifts, andsuperlatives, they will be part of an observance that had its humble beginnings 100years ago. On Sunday, May 10, 1908, simple church services in Grafton, W.Va.,and Philadelphia honored the nation's mothers. A bill introduced in the US Senatethat year failed to establish an official Mother's Day, but it set the stage for asuccessful measure in 1914.
