The Ellis Island record connected to this woman on Family Search has a few problems if we are to accept it is for this woman https://www.familysearch.org/ark:/61903/3:1:3Q9M-C959-4WMC?i=121&cc...
The immigrant is listed as Elisabet Harju, a 25 year old woman arriving in the USA in 1906 to join her husband, _NICOLAS_HARJU_
By August 1906 "our" Elizabeth was a 26 year old woman, it is unlikely she would get her own age wrong. The 1930 census lists her arrival in USA as 1905, not 1906. Most importantly her husband's name is Harold, perhaps Timo, not Nicolas and not Harju. She doesn't even have a brother or uncle named Nicolas Harju that might have been incorrectly recorded as a husband.
It looks like you are trying to tie records from different individuals into a single profile.
What we have records for at this point is:
- An Elisabet Harju married a Timotej Remsujeff in Finland in 1901 and the same couple appear to be in Illinois in the US 1910 census.
- An Elisabeth NN married a Nicolas Harju in Finland and immigrated to Illinois in 1906.
Both Elisabeth's have two daughters, the eldest in each case being named Annie.
- Elisabeth Carlson NN who married "Harold Carlson" also has two daughter's, the eldest being named Annie.
Husband(s)
- Harold T. Carlson is a Swede who in 1920 is a farmer in Pennsylvania
- Timo Remsujeff is a Finn who in 1910 is working as a Wire Puller (a skilled craft) in Illinois.
- Nicolas Harju I can find no further records at this point.
Why would a self identified Finn working a skilled craft in Illinois in 1910 change his name completely and move in 1912 to Pennsylvania to take up farming and start self identifying as a Swede by 1920?? As a narrative this doesn't make sense.
