No! I estimated their marriage date based on the 1930 Census "Age at first marriage". On Monday, call the County Clerks in Bell and Tom Green Counties. Request marriage lookup in the index for this couple in 1927. They should comply with your request 'cause all Texas' County Clerks have marriages indexed by Brides-by-time periods and by Grooms-by-time periods.
