In 1859 there is a William Henry Dorricott, Shelton but unfortunately no mmn given.
You asked if Jane had been married before, I cannot see a marriage to John Dorrycott yet in the census they are living as married.

It may be worth thinking about ordering the 1859 birth record of William Henry DORRICOTT from Stafford BMD to confirm whether his mother's maiden name is PIPPETT, I don't know whether you can ring and make an inquiry.
I cannot find a marriage either for John DORRICOTT (have tried various spellings) to anyone named Jane
The reason I asked whether Jane was married before is that her father is named as Samuel PEPPER on 1872 marriage to Job WARREN and she is named as Jane PIPPETT, if she had been married to John DORRICOTT wouldn't she have married Job using her married name

(
I wonder who the witnesses were to this marriage)

What about there being no father's name on the marriage certificate of William PEPPITT to Emma BAILEY in 1882
