On the 1930 census I do not see Richard or Harriett in Brown Co, TX.Looks like son Patrick and his wife and daughter are there.
Have you sent for the TX Confederate widow's application for Harriett?It was rejected, but one of the good things about government records, even when rejected they keep the record.You never know what will show up on those applications, sometimes even information that wasn't required.A woman had to show proof she was married to the deceased veteran, so date and location should show up.Her husband is listed as Richard Barton Bennett.That alone gives you his middlename.
TX State Archives in Austin has a TX state wide death index 1903-1940, which would give you date and county of deaths for Richard and Harriett.Death certificates should show names of their respective set of parents.With full date of deaths you could look for obituaries.Since he was a doctor, it is more then likely he would have an obit.Again, you never know what will show up in those obits.
Have you checked out the Brown Co, TX GenWeb site?Among other things they have a list of volunteers who will do specific lookups.Maybe someone could check death records for Richard and Harriett.But, if they didn't die in Brown Co, TX the records would not be there.
