I really liked golden pouch, so i recommend.  I've watch 56 out of 122 eps.   Also, its not just family but has romance.
50ish.....All About My Mom, Five Enough, What Happens to My Family, Wang's Family, Glorious Day

100+ episodes......Smile Dong Hae, One Well-Raised Daughter, Ugly Alert

Those were the better ones, but there are plenty of other decent ones, I have been venturing into 50+ episode dramas a lot more.
