McCullough - McCully of Port Greville

Would it be safe to say sons, Toahaways?, Amos, and Engley? are children of
John McCullough and his m/1, Mary Jane Kerr?

Laurretta is actually Larvela Cora, d/o John and his m/2, widow, Jane
(Hazel) Welch?

Clarence, Millard and Henry are actually Florence Elenora Welch, Millard
Welch and David Henry Welch from Jane's m/1 to David Henry Welch?

Thanks in advance for any insights.
