本研究的主角林維龍，是梅鶴山莊第三代，為林萬德（1853-1895）之子，梅鶴林家開創者林登雲（1815-1888）之長孫，自幼飽讀四書五經，亦曾以塾師為業。日治後多任大溪地方要職，諸如保正、庄長、公學校學務委員等，堪稱當時大溪的地方菁英。目前由林家後人提供，中研院所收藏的《梅鶴林家文書》中，有數本林維龍手記私帳，年代橫跨31年度（乙酉-乙卯1885-1915），主要內容為林維龍與妻子蕭氏及其子女的家庭收支及借還款紀錄，這筆私帳不僅保留了豐富經濟與社會活動訊息，且完整呈現了當時地方菁英的生活樣態。透過帳簿內容的分析與梳理，可確實掌握林維龍的理財策略、生活嗜好及社交應酬，其所呈現的個人形象，是一位受過科舉教育的地方富紳，重視親友間的人際互動，理財方式傳統、循規蹈矩卻非沒有彈性。不過，在大家族生活下，其資產可能為家族共財，不得隨意支用。雖然日常飲食之供應不成問題，維龍若有其個人的嗜好或社交活動，就得尋求其他的收入來源。帳簿上所記錄的各項收入，比較傾向於維龍小家庭的日常開銷，其中買賣豬羊與放貸生息，應是林維龍主要的副業及金流來源。
