Can't help but chuckle that the examples of historical priority --
rDNA, globin, and histone genes -- were omitted in favor of these other
valid examples. The molecular, biochemical, & genetic data supporting
gene families in eukaryotes, even with tandem-array organization, began
to appear long before DNA cloning & sequencing, and certainly long before
genome-projects arose as technical possibilities.
A classic pre-cloning reference on eukaryotic gene families is
the review by Hood, Campbell & Elgin (1975) Ann. Rev. Genetics 9: 305-353.
