Eich teulu yw'ch priod, plant dan 21 oed (neu sy'n ddibynnol arnoch), yn ogystal â'ch rhieni a'ch rhieni-yng-nghyfraith os ydynt hwythau'n dibynnu arnoch.
Your family is defined as your spouse, children under 21 (or dependent on you), as well as your parents and your spouse's parents, if they are also dependent on you.
