This includes a map file and a ped file. The map file has one line per SNP and the following columns: chromosome, rs#, genetic distance (blank) and position. The ped file has one line per subject and the following columns: Family ID (anonymous identifier), Individual ID (always 1, as subjects are unrelated), Paternal ID, Maternal ID (both zero), sex (1 = male, 2 = female) and phenotype, which in this case is the number of declared Jewish grandparents.
