jamesjohnson on Family Tree Circles

looking for ANDERS GUSTAVE JOHANSSON THE FINNISH equivalent of ANDREW JOHNSON family in FINNLAND of my great grand father who jumped ship in Tasmania Australia in the 1880s onwards. He was known here as ANDREW JOHNSON. His father was ANDERS AUGUSTUS JOHANSSON a shoemaker. His mother was MARIA JOHANNA ( could her MAIDEN name have been KALSTOM, KULSTUM OR SIMILIAR) He had a brother Charles JOHANSSON who I believe may have been a watchmaker in Finnland.
City / Town in Finnland unknown. Thank you for reading.
