Algol family, which C definitely isn't part of.

It is composed by Mesa, Cedar, Modula-2, Modula-2+, Modula-3, Oberon, Oberon-2, Active Oberon, Oberon-07, Ada, Spark, ParaSail, ...

If you zoom out far enough, few (for example, from a few miles away with my eyes almost closed, I would put Algol and C in the same family: procedural and with block scoping).

There are quite a few distinctly other languages, though. To name a few: APL, COBOL, Forth, sed, Snobol.

Pascal?

This is a very interesting and complex question. CTM provides some answers, summarized in http://www.info.ucl.ac.be/~pvr/VanRoyChapter.pdf
