Hi David,
Maybe the visit to Sittingbourne was connected with the death of Celia's mother, Esther Knowler (nee Read?) death registration in 1949 June qtr.Sittingbourne district, age 52. ref:BMD
George Knowler appears to have married at least three times after being left widowed, 1877, 1910 and 1915.
