I'm trying to delve into the history of Aro, but I'm stuck at my great grandparents. On my grandfather's birth certificate it says Unknown as the father and Margaret as the mother.

I'm pretty sure I found the right Margaret, but it's hard to say for sure not knowing her maiden name. I think his father's name was Henry or Harry, born on or around 1878.

Anyone else hit a roadblock at Harry or Henry Aro?
