It looks like there is a connection between the Twiggs you have listed and my Ann Twigg. Her father, Hugh Twigg, died January 1, 1871. At the time of his death he resided on Conway,His wife, Mary, died 10 years later, January 24, 1881.At the time of her death she resided on Conway.
Ann Twigg and her husband James Hughes were living at 164 Conway when their twin daughters Susan and Catherine were born in December of 1864.They were still there when Susan died in March of 1866,When James died in 1873, they were living at 61 Ross, which according to family lore was also where he was born. Thank you for the information you sent.
