My grandparents were Presbyterian missionaries with the Nez Perce Indians around 1912, Rev A Roy Thompson and Dorothy Thompson, and later in Puerto Rico wher my father was born in 1916.   We have a family grace and I am looking for its source or other variations:   We thank thee Farther, wise and good, for Christ and home and daily food. Bless to our use this food we take, And keep us all for Jesus' sake.   Comments please. Thank you.
