The Spiers family began their overland journey as part of the Outhouse Company. However, the Outhouse Company experienced divisiveness and for much of the way, each ten in the company traveled independently. William Lang was captain of the ten they split off with.

Outhouse Company records show John Spiers as head of household, whose traveling group consisted of two adults and three children. The Lang Company records identify the individuals in his group as his wife and daughter and two other children, Jesse Cook and Elizabeth Goodson. It is uncertain what their relationship was with the Spiers Family.
