I am looking for anyone out there with the Iverson surname in their family tree that has ALS that runs in your family. My grandmother's maiden name was Iverson and 4 of the 5 siblings died from ALS. So did my mother. I have names going back to Marie and Martinus Iverson. Marie's maiden name was Anderson and she was born 2/15/1856 in Varmeland, Sweden. Martinus was born 5/17/1859 and was born in Fune Trestefel, Norway. If these names or the ALS situation applies to you, please contact me. Thank you very much.
