Separating/ merging name quandary

In attempting to update the song-writing details for "Li'l Red Riding Hood" by Sam the Sham and the Pharaohs, I have come across a problem. 

There are 14 entries for “Lil’ Red Riding Hood”, of which the songwriters credited are

• Ronald Blackwell – 9 credits
• Ron Blackwell – 2 credits
• None – 3 credits

There are 4 entries for “Lil’ Red Riding Hood”, of which the songwriters credited are

• Ronald Blackwell – 1 credit
• Ron Blackwell – 1 credit
• Ronald Blackwood – 1 credit
• None – 1 credit 

There are 4 entries for “Little Red Riding Hood”, of which the songwriters credited are

• Ron Blackwell – 2 credits
• None – 2 credits

Ignoring the entries where there is no songwriter credited and the entry for Ronald Blackwood, this leaves two possibilities as the songwriter’s name. 

It could possibly be two forms of the same name (Ron/ Ronald), in which case a simple merge of the names would eliminate any duplication. The preferred name would be ‘Ronald Blackwell’. A scan of major music discography websites provide the following data:

• DISCOGS – uses ‘Ronald Blackwell’ as the heading for the artist’s entry, but uses both ‘Ron Blackwell’ and ‘Ronald Blackwell’ as forms of the songwriter’s name.
• ALLMUSIC – uses ‘Ronald Blackwell’ consistently
• 45CAT - uses ‘Ronald Blackwell’ or ‘Blackwell’
• SECONDHAND SONGS - uses ‘Ronald Blackwell’

while WIKIPEDIA uses 'Ron Blackwell' (qv).

However, 'Ronald Blackwell' has 1 credit as an actor and 'Ron Blackwell' has 4.  These credits all occur in the period 2010-2016. (The song was released in 1966.)

So, there could be one person who is both a songwriter and an actor, or there could be two people – a songwriter and an actor, or there could be three people - two actors and a songwriter. 

I would like to simplify these entries, but my research (limited to the web and my small library of music books) has not assisted me in differentiating or consolidating these individuals. I have not been able to find any biographical data for the songwriter or the actor.

What should I do? Leave as is?

Or do you have access to other information which could assist?

(My gut reaction would be to consolidate all the songwriting credits under ‘Ronald Blackwell’ and all the acting ones under 'Ron Blackwell'.)
