I don't know Margaret's surname prior to marriage. The recently dead realative who's parents are Andrew and Margaret . Their marriage not on the birth certificate of the dead child they had. I think they were gypsies they may have travelled around. Thank you kindly for help. Not had best start on here. Still learning please bare with me
Sad to hear your start with RC has been tricky

Don't be disheartened please. These things sometimes happen anywhere. Great group here who are happy to help and work with you, just because they have access or experience to information sources that you may not.
A key thing here on RC is the protection of people's privacy and information for those still living. RC like people being discussed to be TRULLY dead (in the nicest possible way

)
We need to help you find some hard fact to work from, and us in trying to help.
The only marriage I can see on SP between an Andrew McPhee (with wild cards for spelling variations) and a Margaret during 1910-1940, looks to have been in 1922. This Margaret showing as Maggie McMillan. Marriage in Knockbain, Ross & Cromarty.
