The following cousin family tree helps you understand that your third cousin was twice removed. As per the cousin family tree chart, the third cousin would be the great-grandchild of your great-great-aunt or great-great-uncle. In a general sense, twice removed means a two-generation difference between the two concerned cousins. As illustrated here, the third cousins are always relatives from a genealogical perspective. Even if they are twice removed, there are many chances that the cousins will share the D.N.A.
