Is this usual

Pretty common, here, in Mid Ulster. 

I know of people from school, who I believe have been diagnosed as adults. At school no one thought of Autism as they didn’t fit the “stereotypes”’for Autism.

I think so yeah. Autism is more known now and heard about so more and more people are getting diagnosed early and later in life.

My brother was diagnosed first, then my sister and now me. I have eight cousins and five are on the spectrum.
