With a high dexterity and low charisma, this character would have been a natural thief, but the party needs a cleric, so with a wisdom of 16, he's a cleric. Meet Reffold the Scruffy.
Rolling All Dice, my results were d4: 3; d6: 6; d8: 6; d10: 2; d12: 12; d20: 15.
The d4: Family Reputation
With a roll of 3, Reffold's family is "Respected" (not surprising since they produced a priest).
The d6: Personal Relationship
With a roll of 6, Reffold is "Favored" in his family (not surprising since he agreed to become a priest).
The d8: Number of Siblings
With a roll of 6, Reffold has six siblings. I'll roll 1d8 to determine his birth order (rerolling if the result is 8). Randomly determining the sex of each in order (evens vs. odds), they are: sister, brother, sister, brother, sister, Reffold, sister.
The d10: Extended Family in Household
With a roll of 2, there is a maternal grandfather in the household. He's a quiet fellow, but he has reservoirs of wisdom he occasionally shares.
The d12: Family Occupation
With a roll of 12, it's another family of woodsmen. We'll make them loggers (and secondarily carpenters). Reffold will have some knowledge of both professions. And the family, being respected by the community and proud to have a son in the clergy, has probably contributed lumber and labor in the construction of churches and hospitals. Such a family of do-gooders needs a surname: Woodfell will do. Reffold Woodfell, sometimes styled "the Scruffy."
The d20: Motivation for Adventuring
With a roll of 15, Reffold's reason for adventuring is "Rejection." This is at odds with his favored status in a respected family, so we'll say he was rejected by his religious order and he is seeking to atone for something (probably an unfortunate social gaffe exacerbated by his below average charisma) so he can rejoin the order.
Growing up the favored sixth child amongst seven in a family of respected and devout loggers and carpenters, including wise old Grandpa, Reffold entered the clergy and made the Woodfell clan proud, but a blunder made worse by his deficiency in social skills caused him to fall out of favor with his religious order and now he must atone. He has been cast out until he can return with proof that he is worthy to rejoin his order.
