Berta had a love of people (children and adults), animals and a great joy in life itself! She had a warm, infectious smile that would make anyone feel better just to be around her.
If Berta's essence could be put into a magic pill, the whole world would be Disney Land!
Berta was an only child who longed for siblings growing up. Later, as a teenager and young adult, she longed for nieces and nephews. She said she felt so lucky when she married "her Denny" because he came with a huge family. Suddenly she had the sisters and brothers and nieces and nephews she always wanted in great measure! But, in my opinion, it was we, Denny's family, who were the lucky ones to have Berta join our family!
