The first three siblings are 66 +66 + 60 = <<66+66+60=192>>192 inches tall.

Since the total of all the siblings is 330 inches, Eliza and the last sibling are 330 - 192 = <<330-192=138>>138 inches tall combined.

If Eliza's height = h, 138 inches = h + (h+2).

(138-2)/2 = <<(138-2)/2=68>>68 inches.

Eliza is 68 inches tall.
