Immigrants who married in the new country may have known each other in their homeland. If you know the overseas origins of one member of a couple, try looking for their spouse in the same original area.
But it is possible they were also from different locations and had no knowledge of each other until their arrival in the new country.
Don’t conclude without evidence.

Going back to the 1600/1700 in Yorkshire, my 2nd great grandparents family lived about 60 miles apart in Yorkshire. One side in West Riding, the other side in East Riding. I suppose it’s possible they might have known of each other. 60 miles seems like a long way but compared to crossing an ocean and half the distance in America… maybe it was possible.
