Dobbin Links

JOYCE LAURA GRANT nee Dobbin, my Birth mother, was a daughter of HARRY DOBBIN who was married to Elsie W. BIRCHENOUGH.
Mrs.Grant had me adopted to WILLIAM CHARLES GREEN married to Edith Doris AMES.
Edith Doris' father was HARRY AMES married to Emily Elizabeth (LEWIN).

I am interested to know if there may be any connection between the families of DOBBIN and LEWIN in particular.
