I think anything is possible with this one
I'm not sure that I'm correct with any of the records I've posted, they just seem to connect.
Both the !891 and 1901 census look suspect to me with the Ansborough brothers being step son on one and foster sons on the other one and then 1901 shows a daughter Caroline but I don't think she is Elizabeth's daughter
It's possible that John may not have died but for some reason left the family home in which case Elizabeth couldn't have remarried and I can't see any other marriage for her.
Perhaps you could try tracing Daniel after 1891 see if you can find more about him.
If the 1880 marriage for Dooling is correct then the marriage cert might throw some light on it.
