need help please

Today after exhasuting my leads I opened a 'The Church of Jesus Christ Latter-day Saints' Free Account only to find that information I already have received in the past from Duluth, a 1900 Census, marriage certificate for my paternal grandparents, birth certificates for my father, uncle and two aunts, this Free Acct site says these people cannot be found-I find this strange. The Norwegian Emigration Center paying service at www.emigrationcenter.com is not up and running due to a shortage of staff. I cannot access Duluth Library info unless I live there (I am in France) I am looking for any American side information for a great Aunt Antonette Katinka Maria Mortensen, landed in Duluth on the Thingvalla (pass lists not helping) she landed in September, 1892...from a 'newsarch.rootsweb' partial message on line I know this woman married and had a family but I know no more...any ideas would be appreciated?
