last 2! need birth records

Hello, I'm cleaning up my grandmother's records and do not have birth records for Josephine Olsen, 8 February 1862 Emma Ovidia Olsen, 1869 both daughters of Jens Olsen and Ellene Henriksdr. The family is found in the Nes Parish in Hedemark, but are in Christiania/Oslo by the 1865 and 1875 Census. The census says Emma was born in Christiania. Ironically, Josephine is the one with the best records once they get to the US! Here's my OP: /forum/duplicate-names-help-needed/ I'm not having any luck, but you folks seem to have special powers.
