I might be able to help, as my great uncle married a Hansen (usually misspelled "Hanson" in records) who was born in 1888, but I'm confused by the information you're providing. If you can line it up for me, I might help.
If you can Tell me what you know about Person #1 and separately what you know about Person #2, including where/when born, lived, married, parents names spouses names. Maybe a timeline. Also, "Betty" is usually a nickname, so if you have evidence that it might be Beatha/Bertha/Beata, that might help, too.
