I need some help and advice in filling the job application form.

1) For family background, stated requested my father and mother's details but I didn't live with them since young (raised by my aunt) so I should put my aunt as my mother and N/A in father section? I worry they may ask me about my family background cause it's quite complicated to explain. If they require any details from my parents, I don't think I can provide.

2)For references, I need at least two references but I barely had anyone since I just do some freelance job. So, I include my internship supervisor and ask permission from my lecturer which I'm close to but she rejected. I know that the HR may call the reference for checking so I don't dare to simply put my previous bosses (I don't think they remember me since its been more than a year)

So how should I fill in these ?
