Denying of tradition?

Personally I believe that women taking the last name of their spouse is perfectly fine. Last names can hold long lines of family history one example is that of my last name Bentler. The last name Bentler evolved from my families name of Blumenfield. Richard Blumenfeld my great great grandfather created a huge monopoly based ovens in Germany and was extremely successful in many other fields as well. Today in the town of Velten, Germany they even have a museum in his honor. Many years later during World War II the Nazis seized the family fortune he had amassed and placed my great grandfather who was a well known chemist at the time into interrogation because of his Jewish background reflected by his Jewish last name. After many unsuccessful attempts at bribing his freedom my great grandmother eventually achieved my great grandfathers freedom with the trading of her car. After raising my grandfather and great uncle they decided to leave the outskirts of Nazi Berlin and came to settle in Beverly Hills California in the mid 40's. To start new they changed the Jewish last name of Blumenfeld to the name Bentler. Having this sort of history behind a name and knowing that if I were to have a son, the name and the history that follows, would continue on is exciting. I personally do not believe that the dropping of a last name is a bad thing or that it is done to make women feel inferior, but that it unites a couple and guarantees that the name is carried down at least one more generation. Historically if the last name of women were to be taken I would be perfectly fine with that today, but to change tradition and potentially lose track of a families lineage is a sad prospect. This in no way is a reflection on my feelings toward women or societal roles as I feel that men and women are equal, this is just my belief based solely on tradition.
