Looking for children

I'm wondering if Gotfred Antonius Sybrian Ambrosius Olsen born 10 May 1881 in Trondheim, who married Katherine born in Ytteroy on 8 Nov 1874, had any children? Gotfred and Katherine are listed on the 1910 census in Trondheim, but I have no other information. Gotfred was the son of Sivert Andreas Olsen (1855) and Anna Gurine Olsdtr (1854). Can someone kindly help me with this request? I'm also wondering if perhaps someone knows why Gotfred was named with such Roman names? Thank you!
