Interesting. As for the family connection - possibly. My great grandfather moved from Pajala Sweden - NYC - Butte, MT. I am not sure when he passed on. He had two sons (Gunnar and Walt). My grandfather Gunnar had one Son (Edward), my father. Walt had no sons. I am the youngest and last male Aro.
I have been doing a little research on the internet regarding Aro family history. It looks like most Aro's are from the same area in Sweden - thus we might be related.
