I'm afraid this information won't help you find descendants of Mona and Eli but it could be of use to you:
The birth of Mona M STOCKFORD (mother's maiden name NEWMAN) was registered in December Qtr 1911 in Woodstock Registration District. There was also a Samuel J. S. STOCKFORD registered in December Qtr 1915, same mother's maiden name, same Registration District.
The only STOCKFORD/NEWMAN marriage I could find was in December Qtr 1896, Woodstock Registration District, between Joseph Herbert STOCKFORD and Annie Elizabeth NEWMAN.
Joseph Herbert STOCKFORD was registered in March Qtr 1878, Woodstock Registration District, and Annie Elizabeth C. NEWMAN was registered in June Qtr 1877, same Registration District. In the 1901 census this couple are living in Dornbrook Road, Steeple Barton, Oxfordshire. Joseph is listed as aged 23, a butcher, born Middle Barton. Oxfordshire, and (Annie) Elizabeth is also listed as 23 years of age and born in Duns Tew, Oxfordshire.
Woodstock Registration District ceased to exist in 1932 when it became known as Ploughley.
