I've been tracking down my grandfather, John Anson, and finally found his family page here:

It turned out he was born Juhan Hansen (despite the name listed as "Hanson" in the above document). I've found his birth entry pages in the Karja section of the saaga site, and I found his father's and brothers and sisters birth entries as well. The Personaalraamat documents are poor for the kogudus - any ideas on researching further back ?
I'm also interested in searching forward to see if there are any descendants of my grandfather's brothers and sisters. My grandfather moved to Canada in 1910. From the above document it looks like his sister Miina married in New York in 1911. I also know that his brother August was a witness at Juhan/John's 1922 first wedding. But that leaves 4 others.
It's a long story but before a few days ago I didn't know my grandfather's birth name or if he had any brothers or sisters.
