do i have any ancient celtic lineage/ancestry?

Probably. Exactly how much is the real question, and we can't tell from here.

Hard to tell, but considering your mothers ancestry you most likely have some Celtic ancestry.   The year you were born, your sex and the fact they your parents are elderly has nothing to do with your Genealogy.

Assuming your mother has a long list of Manx ancestry, you are sure to have Celtic from Isle of Man.  Spain at time of Roman conquest was largely Celtic.

Possibly.  Possibly not.  You'd need to do a lot of research to discover this and a REAL DNA test - not one of the 'just for fun' ones they advertise.

Just interested, but why did you think that telling us that your parents are elderly would help or be relevant?

Your surname would be a better indication of your ethnicity than your place of birth (or that of your parents).

Without doing any actual geneaological research, we cannot tell you. 

There's a good chance you have Celtic ancestry on both sides of your family. The Celts inhabited much of the Iberian peninsula, and were amongst the first settlers of the Isle of Man.

In addition to this, from your fathers side you may have north African, sub-Saharan African or Arabic ancestry, from the Islamic invasion of Europe (c.700 - 1400). The Moors were of North African (Berber / Arab) descent and occupied much of the Iberian Peninsula for almost 900 years; they brought with them a large number of sub-Saharan Africans as slaves and soldiers, and Sephardic Jewish ancestry.

Your mothers side may also contribute Gaelic, Saxon and Norse ancestry from subsequent invasions and settlement of the Isle of Man, and also possibly Ashkenazi Jewish ancestry from the Jewish refugees who fled Germany to the Isle of Man in the 1930s.

Celts are identified by their use of a Celtic language, as well as other cultural similarities.

Pertaining to your family connection to The Isle of Man, the Manx language (Manx Gaelic) is a Goidelic language of the insular Celtic branch of the Celtic language family, itself a branch of the Indo-European language family. 

The Isle of Man registers a YES as ancient Celtic because of the Manx language (and it's related Manx culture). 

Pertaining to your family connection to Spain, the residents of Spain claim a Celtic heritage, but no Celtic language is spoken / or, no Celtic language has survived.

Spain registers a YES as ancient Celtic. Tons of ancient Celtic traditions and culture still exist in Spain. Although no ancient Celtic language has survived in Spain, the ancient Celtic culture remains there.

Simply put. The answer to your question is yes! You have ancient Celtic lineage!

All the best.
