Charlotte Jacobson - My current Brick Wall

Location: [unknown]
Surnames/tags: Jacobson McConnell Burg

Charlotte was born in Sweden in July of 1847 and died about 1920 with a strong possibility in New York. Her maiden name is questionable. Married William Henry McConnell in 1880 he died in 1894 leaving two or more children with Charlotte. One of their children by the name of Anna shows up on several censuses as Anna Qwik/Quick married to Richard listing Charlotte as well in her senior years as widowed with the last name Jacobson or McConnell. Also found on a census is a Charles A. Jacobson that strongly hints as a spouse to Charlotte but it shows she was 6 or 7 years older which leads me to think if this could be her younger brother instead of a spouse.
