Thanks so much for your response! Here's what I found on a different website - I did find Ingeborg in the 1865 census for Stavanger.Her full name was Ingeborg Marie or Marie Ingeborg Egeland, but she went by Marie Egeland in 1865.Her birth year is listed as 1846.Her parents were Jesper (b. 1815) and Ane Egeland (b. 1813).Her sister was Josephine (b. 1854), and her grandfather was Erik Egeland (b. 1786).
Anyway, now I'm stuck.I guess the 1875 census is incomplete for some reason - do you know why?I could not find any Egelands in 1801 in Rogaland, but I might not be searching correctly at the site that you gave me.
Let me know if you see a link from my family to yours, or if you have any more ideas for me!Thanks again!
