So, even though William, as the informant, states on Ada's death certificate that he is her son, clearly he has stated different parentage on his marriage certificate. I was also wondering if he was Ada/Patrick's first sons child and he was raised as one of their own kids but the person who responded to my letter doesn't seem to know anything about this. She was married to one of Sidney Arthur's sons.
If you want me to attach copies of the transcriptions/certificates that I already have, let me know.
Hope this is what you wanted JM
thanks for helping
