Looking for information on Robert Mertin MacLean from Melrose Ma. he had 2 brothers Arthur and Alvin along with two sisters Myrtle and Leona. Robert b.8/14/1923 d.10/29/02 Alvin b. 5/7/1926 d. 5/1/1988 Myrtle b. 7/23/1938 Leona b ? Arthur b. ? There has always been some controversy as to whether they are from Irish descent or Scottish. I have several genealogies I can follow once I get the links back a few generations. Any guidance would be helpful.
