Claiming that "we already have enough watercolor painters," Alfredo Roque Gameiro encouraged his youngest daughter, Màmía, to paint in oil instead. If he was worried with lack of variety, he worried in vain. While Helena followed closely on her father's watercolor footsteps, Raquel and Màmía would distinguish themselves as illustrators, whereas Ruy followed the path of sculpture.
With the addition of the two younger sons-in-law, the clan widened its artistic breath considerably. José Leitão de Barros, having started as a watercolor painter, around the age of 30 declares himself a "defunct painter". He would lead numerous projects and ideas (including the 1940 Portuguese World Exhibition) and develop an intense activity in the field of cinema. Jaime Martins Barata, José's colleague and friend at the National Fine Arts Society, would distinguish himself in large-scale painting (especially fresco painting) as well as designing stamps and coins.
