There's another problem I encountered during my fruitless search for the identity of Edward Flanagan in Chicago: the huge gaps in time between each sighting of a Flanagan relative in Chicago records. These Irish immigrants might have blended into the cityscape merely from the sheer numbers of their countrymen who also chose this new-to-them home, but when looking for specific individuals, they sometimes disappeared from records for decades at a time. I'm beginning to wonder whether they had discovered the knack of becoming invisible.
Take Anna Flanagan Malloy and her daughter Catherine. True, tracing a surname like Malloy was a challenge in its own right. I found Anna under multiple spelling variations from Malloy through Mulloy. But after her appearance in her brother William's household in 1860, I couldn't find her again in census records. Not until her obituary in 1885 did I find any mention of her name.
Likewise for her daughter Catherine who, following that one census appearance with her mother in 1860, disappeared from view until the 1900 census, long after she had married John Tully. Before that century mark, she was more likely to be found in the church records of her children's baptism, or in the obituaries of family members. Governmental records in the city seemed to turn a blind eye to some Irish immigrants. Perhaps in the sheer numbers of urban life, immigrants disappeared into the grayer fringes of the picture.
Gaps left from 1860 to 1900 represent a significant portion of adult life, not to mention the life story of multiple immigrants' journeys. I am trying to discover alternate ways to document these ancestors' existence, but perhaps this will call for more inventiveness and creativity than a genealogist is accustomed to mustering. Learning the ropes of life in 1800s Chicago has been my sideline this month, but I'm running out of alternate routes to explore.
