Eric's bio in Irish Astro Journal[ http://adsabs.harvard.edu/full/1975IrAJ...12..112C} confirms Muriel and Sylvia are sisters

Oxford Journal bio article on Eric [3] that describes Sylvia as "a former assistant astronomer at the HCO and discoverer of the first dwarf galaxy, the Sculptor system (Shapley 1937, 1938a and 1938b)." Then adds, "She was a daughter of George and Stella Mussells and was born in Danvers, Massachusetts, graduating from Radcliffe College in 1930. Her sister Muriel was married to Carl K Seyfert, known for the Seyfert galaxies, with their bright nuclear regions displaying abnormally large amounts of high-velocity gas in their central regions (Seyfert 1943). The Lindsays went on to have just one child, Derek Michael Lindsay, born in 1944. He eventually became professor of chemistry in the City College of the City University of New York. Derek died in America in 1999, six months before his mother Sylvia's death in December at the age of 92."
