Summary: We have now traced back Carl Frederik Christophersen b. 29 april 1880 in Bragernes/Drammen, Buskerud county of the parents Frederik M. Christophersen + Inger Elise Carlsen (also called Inger Elisabeth Pedersen and Inger Elise Pedersen) both parents born 1857. They lived Konggaden in Bragernes/Drammen. In 1900 census this family lived in Nedre-Eiker at the gard (farm) Mjøndalen in Buskerud county, with some more children born also in Drammen, Buskerud County <https://digitalarkivet.arkivverket.no/ft/person/pf01037120001947> Inger Elise's parents have been: Shipscarpenter Carl Antoni Pedersen + Karine Johansdr. Elise was born in Skouger (Skoger) parish, Vestfold county. They lived in 1857 at Hedensrudtangen <https://media.digitalarkivet.no/en/view/1134/109> The father Frederik Martinus Christophersen is born in 1857 see here: 6-9-1857 born 1 Juny 1857 Baptism of Frederik Martinus his parents Olavus Christophersen, arbeider + Anne K. Olsdr. Address Konggaden <https://media.digitalarkivet.no/view/1065/108> Frederik Martinius father: Olaves Christophersen was mentioned in 1865 census to have been born in Hof's prestegjeld ~1828, which could have been Hof in Hedmark or Hof in Vestfold. Unfortunately I could not find a wedding between Olaves Christophersen and Anne K. Olsdr in Bragernes/Drammen (I think the year is missing and forloververklarung are horrible to read.) I could not find a baptism in Hof parish in Hedmark in between 1827-1829. But in Hof parish, Vestfold county there was a baptism in 1828 of "an" Olaus Christophersen born 23 July 1828 of the parents Christopher Olsen Romseberg? (Rønneberg) + Berthe Taastensdr? #21 <https://media.digitalarkivet.no/view/8134/59> I would not know how we can check if this is the right Olavus Christophersen b. 1828. But Virginia: tell your friend that, except from visiting Bragernes/Drammen in Buskerud county and Skoger plus Hof in Vestfold county, there are 3 beautiful old stavechurches in Buskerud, Your friend certainly must visit those 3 stavechurches. Nore and Uvdal and Rollag Stavechurch <https://no.wikipedia.org/wiki/Liste_over_stavkirker_i_Norge> And driving by car in Buskerud county is like visiting a museum all the time. Everywhere old buildings, old farms along the road and there are more stavechurches in Buskerud to visit. Flesberg, Gol and Torpo are also in Buskerud county. So I whish your friend a good trip! Reina
