Veronique and Anne pose with their twins, Angele and Lucien, in Brest, France. The same-sex couple had to travel to Belgium to get the in-vitro fertilization they couldn't get in France, said photographer Vincent Gouriou.
Sandrine and Frederique are both transgender and have been together for several months, Gouriou said.
Fulub and Yann-Pier have been living together for 25 years. They bought a house in the countryside together and got married a year ago.
Laurence is divorced and shares custody of her children Noemie and Antoine.
Gouriou met twins Florence and Patricia in a restaurant and went on to take pictures of them at their apartment in Brest. Family is "all about giving and receiving love and affection," Gouriou said. It's about "feeling protected (and) connecting with other human beings."
Melanie, seen here with her father, is transgender. She is supported by her family, her friends and her boyfriend, Gouriou said.
