I am looking for any information on my great-grandmother, Margaret Althea Bruin. She was married to my great-grandfather, Walter Scott Cook in Aspen, Colorado. On the 1900 Pitkin Co., Colorado census she says she was born in PA and her mother in Ireland. I found her brother Frank Laurence Bruin listed in Pitkin Co. WW1 draftees and then found him in the Colorado census and he says he was born in CO and father in MO and mother in MD. She and Walter are in the S.L.C., Utah 1920 census and his obit says that she died in S.L.C. in 1920. Any info would be greatly appreciated.
