If it were me, I would NOT put down titles on personal tasks. A gap of ten years is too long to "hide". I would just put the resume in a regular format, then in that chronological time slot, write a note to the effect of 1995-2005 Took time off to act as primary caregiver for ill family member who passed away in 2005.

But ultimately, this is a very personal decision and you may not wish to include something like that, which is also understandable.  Just note that if you do choose to include it, be sure to indicate that it is resolved.
