Five left to get on my quiz board. I'll give the remaining answers tomorrow.
I thought #3 would go quickly -the daughter is posted frequently and she regularly appears on her daughter's socials.
#6 & #10 are very well known (both have been posted on this thread by people that weren't me) but the mothers are extremely rarely seen (although after making this they both did show up in insta stories yesterday).
#9 is often on her daughter's socials, the daughter isn't posted that much but will be recognisable to most of you.
#12 is the hardest. She does have a thread on starlet, but she is seldom posted and the mother is rarely seen (although her daughter does look just like her).
