I don't know this family personally but have an adoption/virtual friend who does. This family recently moved to Guatemala (with several of their own children) to work (like in missions) with children at a hogar/orphanage. They are working not only with orphans but with children who walk to the hogar to get a good meal each day.
Anyway, tonight she (Amy, the mom of the family I have never met) posted a need.
I could explain further but instead would encourage you to look at the blog and see the shoes being worn and hear the plea in her words...
