Many thanks all.
A few more problems!!
1a. Being descended from the same ancestor (13)I have consanguini??
I know it would be right maybe but I have difficulty with 2 answers out of that.
6d. Narrated (????ed) this depends on answer to 1a.
9a comes into answer for narrated. Clue for 9a Is measuring instrument (5)m?t??
4d. Distinctive practice suffix (3) I have ism
I hope this is clear
Ignore my last 2 answers . Predictive text playing tricks on me.
1a is 13 letters. I got consanguinity or consanguineal.
For 6d narrated I have found a word yarned for narrated??
