For Family History Month and Hispanic Heritage Month we share with you a holiday for remembering and honoring deceased family members and loved ones – Día de los Muertos, or Day of the Dead. Essential to this holiday is the creation of ofrendas, or altars, that welcome and remember the spirits of the deceased. The Hispanic Genealogical Society of Houston has created ofrendas that can be viewed from September 17th through November 9th. Adults/Teens.
