In a previous lessson we learned how to say members of your family. In Japanese the word uchi (うち) is used often to refer to stuff within your home, household or family.
Our home is two people family (There are two people in my family) = uchi wa futari kazoku desu (うちは二人家族です)
My daughter is well = uchi no musume wa genki desu
The word for brothers is kyoudai (兄弟). The word for sisters is shimai (姉妹). In Japanese kyoudai is also sometimes used to refer to both brothers and sisters.
I want a sister = shimai ga hoshii (姉妹が欲しい)
Both parents = ryoushin (両親)
Relatives = shinseki (親戚)
Cousin = itoko (いとこ)
The sound go at the beginning of shujin is another polite prefix, similar to the honorable O. Go and O are not interchangeable. Shujins meaning actually can be translated as master. Because of this meaning, a lot of Japanese women prefer not to use this word.
The word danna (旦那) (My husband) and Dannasan (旦那さん) (Your husband) are more common words used to describe ones husband, especially among younger people.
Are you married = kekkon shite imasu ka (結婚していますか)
I'm single = dokushin desu (独身です)
