Susie, you're right. This is Sigrid Alma Nylén born April 24th, 1870 in Torsång, Dalarna, Sweden and 2nd cousin of my great grandfather Waldemar Carlgren, who owned the album. Now I recognize her from other photos. Her parents were Alma Sofia Melkersson born May 6th, 1850 in Apeboda, Dalarna and Gustaf Theodor Nylén born April 5th, 1836 in Säter, Dalarna. Sigrid was called Tua.
