I would like to have some information about my fathers aunt, Margareth Nilsson born 22 July 1904 in Lännäs, Sweden. She immigrated to Chicago, Illinois in 1922. She married Howard Brown in 1930. They got two daughters, Marianne born in 1931 and Diana born in 1937, who both got killed in caraccidents. Marianne was married to a man named Teddy and had two children, Jonny born in 1951 and Valery born (?). Diana had one child, Tom.
Margareth died 07 Oct 1988.
I've got an adress to her in Indianapolis, 29 Oct 1968:
1222 N. Riley
Indianapolis, Indiana
I would like to have more information about her children, grandchildren and their children.  
Can anyone help me??
