I'm a new member to WikiTree so I can't see the private trees - that's my disclaimer to saying that Ican't confirm for sure that this "your" family or if you already have this information. It looks right given that Margaret age and John is a "Sr." indicating that there may be a John Jr.
The 1940 US Census lists this Conheeney family living with the Bairds, and there is also an Asher living there. John Jr is only 1 year old, so it's you can probably narrow the marriage down, if you haven't already, to about 1938:
Census Place: West Palm Beach, Palm Beach, Florida; Roll: T627_606; Page: 5B; Enumeration District: 50-25B.
