Andrew mckinney lived in Boston on Beacon Hill during this period However I do not know the district in order to locate him in the census. According to the NY Times obit in 1881 He died in Colorado after living in New York City He was a member of the Mercentile ex. It also stated that he was a member of the MASSACHUSETTS LEGISLATURE. If anyone could tell me to to access this ifnormation or has the ability to LOOK-UP- I would certainly be appreciative. During this period he also married to a roberta Walker( as I was told) no proof. Thanks a million AHJ
