Bonaparte was the sire of Louada's long time herd sire, Rothes King if my memory is correct. Seems like the cow you're thinking of was Blood Royal 33rd. In a Louada ad in the 60's, they had King's pedigree back about 8 generations or so. Rothes King, Bonaparte, Bapton Constructor, Calrossie Constellation, Welcome, and Harmony, Lawton President Roosevelt, and some Glastullich bull is the sire progression I remember, though they may not be in perfect order. Our neighbor, Ron Kellogg, bought Louada Rothes Prince, a full brother to Rothes King, from Billy Anderson in the 60's. I bought a daughter of Prince from him and boy was she a producer! I also had daughters of Louada Aristocrat and Meadowview Constructor, both sons of Bapton Constructor. There's a reason Clark became popular 10 years later.
