Only two births ever recorded with the full names of Isabella McMcNeil Paul. So similar in details, how to tell the difference

Isabella McNeil Paul b. 1890 in Dennistoun
Isabella McNeil Paul b. 1892 in Blythswood
One marriage:
Isabella McMcNeil Paul and James McDonald married in 1916 in Milton
Two deaths:
Isabella McNeil Paul, aged 23 died in 1915 in Eastwood. Mother's maiden name McKee.
Isabella McNeil Paul/McDonald, aged 56, died in 1947 in Possilpark.
Do you have any thoughts on which is the correct mother for Angus Jnr.?
