You are incredible. So I dont have much information other than some stories from a distant cousin and research I could dig up here in the US. My grandmother (Martha Tahja born in the US) was the youngest daughter of Matti August Tahja and Liisa (Elizabeth) Tahja. They had 6 children:
Allen A Tahja - born Finland
Andrew M Tahja - born Finland
Elma E Tahja - born Finland
Annie J Tahja - born Finland
August Tahja - born / died on the ship to Ellis island.
Arnold Tahja - born US
Martha Tahja - born US
Matti originally left Merjervi, Finland during due to the war and made 7 trips from Merjervi to CA before settling. Here is a photo I recovered from a museum:

Matti's birthday was May 15 1866. Liisa's birthday was Feb 5 1882. I was told or read some where that Matti's mothers maiden name was Eilola.
Looking to see how to add these profiles. THANKS!!
