Helping out Greta

Hi there my name is Mary Bergen, I am raising money for a family friend, Cornelius and Greta letkeman. They are from Colonia Manitoba, Cuauhtemoc Chihuahua Mexico, Campo 6.5 B AP 357 Casa 1114 C.P.  31607.
She is 56 years old and has blood and nerve infection, she can barely walk. The only income they have is from her husband which isn't nearly enough to pay their doctor bills, and they still have to go to the doctors very often. So they are asking for some help, Any donations are very much appreciated. Thank you and God bless you.
