We have updated the system to allow for same sex partners and parents. Sorry it took so long. When you add a spouse/partner the person defaults to the opposite sex but we have added the option to change the gender of the person that allowing for same sex as partner. Also when adding father or mother you can change the sex so that both parents can be male or female.
When selecting a spouse/partner or father/mother from a list of existing names, we now provide the ability to change the selection list's gender.
