Chump change it ain't.

With a net worth estimated at a cool $2.1 billion, Baltimore's Blaustein brood ranks as number 108 on Forbes' magazine's list of the 185 richest families in America, worth a combined $1.2 trillion.

The only Charm City clan to make the list, the Blausteins made their bucks in the early 20th century, according to the Blaustein Philanthropic Group's website. It seems that Louis, a Lithuanian immigrant, and his son, Jacob, teamed up to deliver kerosene in a horse-drawn wagon through the streets of Baltimore. 

In 1910, the pair named their fledgling business the American Oil Company -- Or Amoco.

Three other Maryland families made Forbes' list, which will be published in the July 21 issue.

They're the Rales family of Potomac (they founded the Danaher Corp., an umbrella biz based in Potomac) with an estimated net worth of $7.9 billion, placing them in 32nd place; the Bethesda heirs to the Marriott hotel chain, with an estimated net worth of $5.7 billion (No. 47) and the Perdues of Salisbury poultry fame, with an approximate fortune of $2 billion (No. 115.)

Granted, the Free Staters are pikers compared to the top-ranking dynasty on Forbes' list, the descendants of Wal-Mart founder Sam Walton. That crew is worth a gasp-worthy $152 billion.

Still, $2.1 bill will buy a lot of pot roast.
