It was not uncommon for a girl to learn her father's trade and for a woman to share her husband's trade, since the entire family often helped run medieval shops and farms. Many guilds also accepted the membership of widows, so they might continue their husband's business. Under this system, some women trained in horse-related trades, and there are records of women working as farriers and saddle-makers. On farms, where every hand was needed, excessive emphasis on division of labour was impracticable, and women often worked alongside men (on their own farms or as hired help), leading the farm horses and oxen, and managing their care.
