I would think the only connection there might be is if my John Joseph Henry was a brother or cousin to your Edwin as they were born in the mid 1820's. Unfortunatley, I cannot find any information re. John Joseph Henry's parents and only know that he was born in Manchester.
What is interesting is that one of Edwin's sons is named Joseph Henry ! So maybe there is a connection - it is just finding it!!!
Also, just re-checked your website and noticed that Edwin's occupation was grocer. John Joseph Henry's occupation was also grocer - so there must be a connection.
I'm going to see if I can find John Joseph Henry on the earlier census listings and also see if Edwin is listed - maybe we can establish a connection if these names show up in the same household.I'll keep you posted!
