A very nice person found a small newspaper obit on Annie Gravos.
Annie Gravos of Cresco born Dec. 17, 1865 age 42 years and 16 days married, born in Norway, father T. Oloerson or Olouson?? of Norway, housewife informant Albert Gravos. Died Jan. 2, 1908 of Bright's Disease. Buried at Oak Lawn Cemetery, Cresco IA.
Isn't that great. So now we have a confirmation of her birth date and death date. Also location of burial and where buried. I have been searching for the T. Oloerson or Olouson but have not come up with much. I found a Thurston Oloerson in Whitewater Township, Walworth Co., WI. But nothing to go with it.
Just thought I would share this great info. Thanks to your help and Janice, I am hopefully on the road to finding my Norwegian heritage.
