- The someone’s mother word uses apostrophe means it is normally used for person and that means we can derived that someone is fourth child. Here instead of someone name of the person can be anything that martin,john etc.
- Second opinion of answer is what is the name of fourth child.
- The final answer you could say is “South”. The sentence contains a chain of names and you could say that since the names are directional, the last name must also be a direction. However, this is the weakest argument because a name does not necessarily have to be a direction. Put it this way, A cat is an animal, but not all animals are cats. The first part being true does not mean the second part is also true.

If colon is used then meaning is different and colon is not used then meaning is different.
- so four sons and then at first time reader seems to make a list of 3 items in a sentence fragment.
- Reading the Ashford’s rules for horizontal lists
- “In a list with three or more items, separate items with commas. Use the word ‘and’ only before the last item in the list, and always follow the last item with the proper punctuation when the list ends the sentence. Rule #7: Use a colon after a complete sentence that introduces a numbered or unnumbered horizontal list.”
- so since you are missing a colon following the complete sentence “Someone’s mum has four sons” one might come to the conclusion that “and” is the 3rd son’s name (even though it is a proper un-capitalized name) thus making Wednesday the 4th son (assuming that your unnumbered list is in numerical order.)
