We are not being aggressive. We are all trying to help but in order to do so we need you to answer the questions we asked (if's okay to say if you don't know the answer to a question but at least acknowledge it).
There are still lots of questions you haven't responded to.
A John P. Carter (mother O'Connor) birth registered in 1923 Hammersmith district, There's also a possible sister Daisy M (1920)- for earlier births we need to do more involved searches. Once we can get back to early 1900s it should, in theory, be easier to find details.
However, I don't think you've actually mentioned your grandfather's name
