I have a “collapsed pedigree.” My great-great grandfather’s line was married into by my maternal grandfather. My great-great grandmother, sister to the GG grandfather, line was married into my maternal grandmother’s line. (Southern MN in the 1860’s). Anyway, these lines end up going back to the Mayflower so there are lots of ancestors to enter into reunion. Is there a way link the brother and sister to import all data? Thank you, first post but I’ve been using Reunion I think since Reunion 5 or 6.
